Highly Selective Asymmetric Hydrogenation of Oximes to Hydroxylamine Derivatives

A recent work published in Science by Cramer and co-workers demonstrates chiral cyclometalated Ir(III) complexes can selectively catalyze the hydrogenation of carbon-nitrogen double bond of oximes with the aid of acid. Various oximes can be hydrogenated to the corresponding N-alkoxy amines in good to excellent yields with good enantioselectivity.

Rendering classical hydrophilic enantiopure Werner salts [M(en)(3)](n+) nX(-) lipophilic (M/n = Cr/3, Co/3, Rh/3, Ir/3, Pt/4); new chiral hydrogen bond donor catalysts and enantioselectivities as a function of metal and charge

Known hydrophilic halide salts of the title compounds are converted to new lipophilic BArf- (B(3,5=C6H3(CF3)(2))(4)(-)) salts. These are isolated as hydrates (Lambda- or Delta-[M(en)(3)](n+) nBAr(f)(-)center dot zH(2)O; z = 17-9) and characterized by NMR (acetone-d(6)) and microanalyses. Thermal stabilities are probed by capillary thermolyses and TGA and DSC measurements (onset of dehydration 71-151 degrees C). In the presence of tertiary amines, they are effective catalysts for enantioselective Michael type carbon-carbon or carbon-nitrogen bond forming additions of 1,3-dicarbonyl compounds (acceptors: trans-beta-nitrostyrene, di-tert-butylazodicarboxylate, 2-cyclopenten-1-one; average ee = 33%, 52%, 17%). Effects of the metal and charge upon enantioselectivities are analyzed. A number of properties appear to correlate to the NH Bronsted acidity order ([Pt(en)(3)](4+) > [Cr(en)(3)](3+) > [Co(en)(3)](3+) > [Rh(en)(3)](3+) > [Ir(en)(3)](3+)).

Synthesis and crystal structures of tetrameric [2-(4,4-dimethyl-2-oxazolin-2-yl)anilido]sodium and tris[2-(4,4-dimethyl-2-oxazolin-2-yl)anilido]-ytterbium(III)

Reaction of 2-(4,4-dimethyl-2-oxazolin-2-yl)aniline (H2-L1) with one equivalent of Na[N(SiMe3)(2)] in toluene afforded pale-yellow crystals of tetrameric poly[bis[mu(3)-2-(4,4-dimethyl-2-oxazolin-2-yl)anilinido][mu(2)-2-( 4,4-dimethyl-2oxazolin-2-yl)aniline]tetrasodium(I)], [Na-4(C11H13N2O)(4)](n) or [Na-4(H-L1)(4)](n) (2), in excellent yield. Subsequent reaction of [Na-4(H-L1)(4)](n) (2) with 1.33 equivalents of anhydrous YbCl3 in a 50:50 mixture of toluene-THF afforded yellow crystals of tris[2-(4,4-dimethyl-2-oxazolin-2-yl)anilinido]ytterbium(III), [Yb(C11H13N2O)(3)] or Yb( H-L1) 3 (3) in moderate yield. Direct reaction of three equivalents of 2-(4′,4′-dimethyl-20-oxazolinyl)aniline (H2-L1) with Yb[N(SiMe3)(2)](3) in toluene resulted in elimination of hexamethyldisilazane, HN(SiMe3)(2), and produced Yb(H-L1)(3) (3) in excellent yield. The structure of 2 consists of tetrameric Na-4(H-L1)(4) subunits in which each Na+ cation is bound to two H-L1 bridging bidentate ligands and these subunits are connected into a polymeric chain by two of the four oxazoline O atoms bridging to Na+ cations in the adjacent tetramer. This results in two 4-coordinate and two 5-coordinate Na+ cations within each tetrameric unit. The structure of 3 consists of a distorted octahedron where the bite angle of ligand L1 ranges between 74.72 (11) and 77.79 (11) degrees. The oxazoline (and anilide) N atoms occupy meridional sites such that for one ligand an anilide nitrogen is trans to an oxazoline nitrogen while for the other two oxazoline N atoms are trans to each other. This results in a significantly longer Yb-N(oxazoline) distance [2.468 (3) angstrom] for the bond trans to the anilide compared to those for the oxazoline N atoms trans to one another [2.376 (3), 2.390 (3) angstrom].

Catalytic Asymmetric Aza-Diels-Alder Reaction: Pivotal Milestones and Recent Applications to Synthesis of Nitrogen-Containing Heterocycles

In this review, the pivotal achievements and recent advances in catalytic asymmetric aza-DAR reported up to 2020 are retrospectively considered and their potency for enantioselective synthesis of useful chiral piperidine, quinoline, pyridazine, oxazine and oxadiazine derivatives and fused compounds of higher molecular complexity bearing these pharmacology-relevant heterocyclic scaffolds is demonstrated. The reported data are systematized according both to key electron transfer modes (normal or invers electron demand reactions) and to main types of attainable heterocyclic products. Of significant attention are an analysis of activation strategies (complexation, enamine or enolate formation, H-bonding, etc.) applicable to reactions with particular types of dienes and dienophiles and identification of plausible reaction pathways (either concerted or stepwise) over stereoselective cyclization processes. The review contains 310 references and 122 synthetic schemes.

Experimental data on synthesis and characterization of chiral dinuclear manganese (II-II) compounds as biomimetic models of the active center of catalase

Dinuclear manganese (II- III) compounds, which are potential models of the active center of catalase, were synthetized. This type of metalloenzymes presents biological importance due to three factors: they are redox catalyst centres, they are able to carry out hydrolytic reactions and they participate in activated processes via Lewis acids. Structurally, their active centre is composed by dinuclear manganese compounds, linked to nitrogen and oxygen donor atoms. An octahedral geometry around the metal ions were found, with acetate, hydroxy and aquo ligands; which can work as molecule bridges between them. The acid medium favours the electronic transfer between Mn3+- Mn2+ as redox centre at 1.559 V and the consequent oxidation of hydrogen peroxide or organic molecules. The work also reports the data of two chiral novel compounds, [Mn-2(S,S(+) Hcpse)(4)(NaClO4)(2)(NaOH)(CH4O)](n)center dot[(C2H6O)(2)](n)center dot[(CH4O)(2)](n) and its respective enantioisomer, in which m-oxo being as bridge metal centre.

A stereoselective, catalytic strategy for the in-flow synthesis of advanced precursors of rasagiline and tamsulosin

The diastereoselective, trichlorosilane-mediate reduction of imines, bearing different and removable chiral auxiliaries, in combination either with achiral bases or catalytic amounts of chiral Lewis bases, was investigated to afford immediate precursors of chiral APIs (Active Pharmaceutical Ingredients). The carbon-nitrogen double bond reduction was successfully performed in batch and in flow mode, in high yields and almost complete stereocontrol. By this metal-free approach, the formal synthesis of rasagiline and tamsulosin was successfully accomplished in micro(meso) flow reactors, under continuous flow conditions. The results of these explorative studies represent a new, important step towards the development of automated processes for the preparation of enantiopure biologically active compounds.

Asymmetric Allylic Alkylation of beta-Ketoesters via C-N Bond Cleavage of N-Allyl-N-methylaniline Derivatives Catalyzed by a Nickel-Diphosphine System

Nickel complexes bearing chiral diphosphine ligands, such as (S)-Tol-MeO-BIPHEP and (S)-H-8-BINAP, serve as efficient catalysts for asymmetric allylic alkylation (AAA) of beta-ketoesters, using allylic amines as ally! sources. The reactions proceed with high catalytic activity and high enantioselectivity. N-Methyl-N-phenyl allylic amines were indispensable to achieve the high catalytic activity, to achieve the high enantioselectivity, and to expand the substrate scope to 5- and 7-membered beta-ketoesters, whose nickel-catalyzed AAA with allylic alcohols results in low enantioselectivity. On the basis of the kinetics using a catalyst system made of Ni(cod)(2) and (S)-Tol-MeO-BIPHEP, and DFT calculations for the reaction pathway of the AAA reaction mediated by an isolated olefin-coordinated nickel-DPPF complex 4b, we propose a mechanism where protonation of the nitrogen atom of the coordinating allylic amine by beta-ketoester is key to cleaving the C-N bond and delivering a cationic pi-allyl nickel(II) intermediate.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 136030-00-7, you can contact me at any time and look forward to more communication. Quality Control of (1R,2S)-1-Amino-2,3-dihydro-1H-inden-2-ol.
