alpha-Trifluoromethylated tertiary homoallylic amines: diastereoselective synthesis and conversion into beta-aminoesters, gamma- and delta-aminoalcohols, azetidines and pyrrolidines

The diastereoselective addition of allyl zinc and allylindium derivatives to a-trifluoromethyl N-tert-butanesulfinyl hemiaminals, bench stable precursors of aryl and alkyl trifluoromethyl ketimines, allows the synthesis of homoallylic amines containing a tetrasubstituted carbon stereocentre bearing a trifluoromethyl group with good diastereoselectivities (up to dr > 99 : 1). This approach was also suitable for accessing chiral homoallylic amines bearing two contiguous stereocenters. The synthetic usefulness of N-tert-butanesulfinyl homoallylamines was illustrated by preparing various trifluoromethylated nitrogen containing bifunctional synthons (aminoesters, aminoalcohols) and small azaheterocycles (azetidines, pyrrolidines).

Catalytic Asymmetric Chemodivergent C2 Alkylation and [3+2]-Cycloaddition of 3-Methylindoles with Aziridines

Highly enantioselective C2 alkylation and inverse-electron-demand [3 + 2]-cycloaddition of 3-methylindoles with 2,2′-diester aziridine were accomplished. The chemodivergent synthesis provided an access to two kinds of chiral indole derivatives in good yields and stereoselectivities in the presence of the chiral N,N’-dioxide/Tm(OTf)(3) or N,N’-dioxide/Ho(OTOf)(3) complexes. An eight-coordinated mode of N,N’-dioxide/Tm(OTf)(3) complex was confirmed by X-ray crystal diffraction to interpret the roles of additives H2O and 1,4-dioxane. In addition, the control experiments indicated that the substituent of the indole nitrogen atom determined the conversion patterns in the divergent reactions.

A novel carbon dots derived from reduced L-glutathione as fluorescent probe for the detection of the L-/D-arginine

In this report, water-soluble carbon dots (CDs) with stable fluorescence (FL) were designed and synthesized by using environment-friendly reduced L-glutathione (GSH) as the precursor and ethylenediamine (EDA) as the passivating agent through a one-step hydro-thermal method. The CDs, with bright blue FL, had the quantum yield (QY) of 40% and showed excellent monodispersity and solubility in water. The FL intensity was remarkably enhanced when a racemic modification of L-/D-arginine (Arg) was added into the CDs solution. Therefore, the CDs could be considered as a sensitive probe for the detection of Arg. Under optimized conditions, the CDs exhibited a linear fluorescence response in the range of 3-124 mM (R-2 = 0.9987) Arg with the detection limit of 2.85 x 10(-8) M. In addition, no evident difference was observed when comparing the FL results of L-Arg and D-Arg. Therefore, this method could not be used in the chiral recognition of two enantiomers. Under optimum conditions, the mechanism and the reasons for the enhancement of FL were investigated. The developed method exhibited great stability, selectivity and accuracy in determining the Arg content in human urine sample and the recovery range was from 97.0% to 102.2%. Thus, our proposed method has potential application in biological molecular recognition.

SmI2 and Titanocene-Mediated Coupling Reactions of alpha-Aminoalkyl Radicals and Applications to the Synthesis of Aza-Heterocycles

Carbon-carbon formation at N-alpha-carbon is an essential transformation in the synthesis of nitrogen containing compounds. N-alpha-Carbocations (iminium ions), N-alpha-carbanions, and N-alpha-aminoalkyl radicals constitute three major classes of intermediates for this goal. The carbon-carbon forming reactions based on N-alpha-aminoalkyl radicals is advantageous over other two classes of intermediates for being able to run the reactions under mild neutral conditions. Moreover, because N-alpha-aminoalkyl radicals are umpolung of N-alpha-carbocations (iminium ions), the approaches based on these intermediates are complementary. In this regard, Kagan reagent (samarium diiodide, SmI2), a mild single-electron reductant, has emerged as a versatile reagent for the generation and coupling of N-alpha-aminoalkyl radicals. In this review, recent progresses on the carbon-carbon forming reactions at N-alpha-carbon via Kagan reagent is summarized. A number of nitrogen-containing substrates including imines, nitrones, hemiaminals, imides and amides have been shown to be valuable precursors to generate alpha-aminoalkyl radicals. The in situ coupling reactions of the latter with aldehydes/ketones, or electron deficient alkenes lead to the formation of N-alpha-C-C bonds. These methods allow flexible access to diverse N-alpha-C functionalized compounds. To overcome some limitations of Kagan reagent, methods based on the titanocenecatalyzed generation of N-alpha-aminoalkyl radicals have also been developed. Many of these methods have been applied to the concise syntheses of medicinal-relevant compounds, alkaloids or key intermediates.

Enantioselective Regiodivergent Synthesis of Chiral Pyrrolidines with Two Quaternary Stereocenters via Ligand-Controlled Copper(I)-Catalyzed Asymmetric 1,3-Dipolar Cycloadditions

An unprecedented ligand-controlled regiodivergent Cu(I)-catalyzed asymmetric intermolecular (3 + 2) cycloaddition reaction of alpha-substituted iminoesters with beta-fluoromethyl beta,beta-disubstituted enones was developed. This novel strategy provides an efficient method for the enantioselective regiodivergent synthesis of pyrrolidines bearing two adjacent quaternary stereocenters or two discrete quaternary stereocenters, opening up a new era for medicinal chemistry and diversity-oriented synthesis. DFT calculations showed that the P,N-ligand L2 acts as a pseudobidentate ligand. The formation of a O-Cu bond with the carbonyl oxygen atom of the enone and dissociation of the amine nitrogen of L2 from the Cu(I) center occurs during the catalytic cycle; this is the main reason for the tuning the regioselectivity of the cycloaddition reaction caused by switching of the ligand. The salient features of this work include high yields (up to >99%), a general substrate scope, the use of commercially available ligands, and high regio-(up to >20:1 rr), diastereo- (up to >20:1 dr), and enantioselectivity (up to >99% ee).

Phosphorus-nitrogen compounds. Part 44. The syntheses of N,N-spiro bridged cyclotriphosphazene derivatives with (4-fluorobenzyl) pendant arms: Structural and stereogenic properties, DNA interactions, antimicrobial and cytotoxic activities

Isopropylaminopentachlorocyclotriphosphazene, (N3P3Cl5(NHCHMe2) (1), containing a P-NH group in the alkyl-chain, gives the NN-spirobridged octachlorobiscyclotriphosphazene, [N3P3Cl4(NCHMe2)](2) (2), in the presence of NaH. The reactions of 2 with excess pyrrolidine result in the formation of the fully substituted bridged product 2a. The reactions of 2 with 1:1 and 1:2 equimolar amounts of N-(4-fluorobenzyl)N’methylethane-1,2-diamine and N-(4-fluorobenzyl)-N’methylpropane-1,3-diamine produce the (4-fluorobenzyl) pendant armed monospiro (2b and 2c) and dispiro (2f and 2g) products. These compounds react with excess pyrrolidine to form stable, fully substituted cyclotriphosphazenes (2d, 2e, 2h and 2i). The structures of 2a and 2f are determined by X-ray crystallography. The stereogenic properties of 2a and 2f having four potential stereogenic P-centers are investigated by crystallography. The monospiro (2b-2e) and dispiro (2f-2i) products have one and two equivalent chiral centers, respectively. The dispiro derivatives may have two meso (trans-trans and cis-cis) and two racemate (trans-cis and cis-trans) mixtures. However, the structure of 2f is found to be as trans-trans (meso) isomer. Besides, in vitro antimicrobial and cytotoxic activities of 2d and 2h are evaluated. The compounds exhibit significant growth inhibitory effects on E. coli and B. cereus bacteria. Compound 2d has high anticancer and apoptotic activities.

Cp*Co(CO)l(2) as Catalyst for Ortho-C,H Activation at Ferrocene: ODG-Dependent preference for 2-Mono- or 2,5-Dialkenylation

The catalytic ortho-alkenylation at ferrocene has been investigated with C-p*Co(CO)I-2 as the catalyst for some nitrogen ortho-directing groups (ODGs). The reaction conditions were optimized starting from 2-ferrocenylpyridine, and a number of terminal arylethynes gave preferentially the 2,5-dialkenylation products in up to 94% yield. In most cases the 2-monoalkenylation products were not obtained, although there are exceptions with formyl- and thioacetyl-substituted arylethynes and ferrocenylethyne. When 1-phenylpropyne was used, the dialkenylation took place with high selectivity. Use of 1-ferrocenylisoquinoline resulted in moderate yields with poor selectivity for the mono- or dialkenylation. With N,N- dimethylferrocenylcarboxamide, however, very high selectivity for monoalkenylation was observed. Products were obtained in up to 90% yield; in only one case the dialkenylation was product observed in trace amounts. All products were characterized spectroscopically, including four crystal structure analyses. The results are explained by the steric hindrance of the N,N-diemethylcarbamoyl ODG when the conformation necessary for a second alkenylation is adopted. In summary, ODGs for the selective cobalt-catalyzed mono- or dialkenylation have been identified.
