C-H Functionalization of Amines via Alkene-Derived Nucleophiles through Cooperative Action of Chiral and Achiral Lewis Acid Catalysts: Applications in Enantioselective Synthesis

Catalytic transformations of alpha-amino C-H bonds to afford valuable enantiomerically enriched alpha-substituted amines, entities that are prevalent in pharmaceuticals and bioactive natural products, have been developed. Typically, such processes are carried out under oxidative conditions and require precious metal-based catalysts. Here, we disclose a strategy for an enantioselective union of N-alkylamines and alpha,beta-unsaturated compounds, performed under redox-neutral conditions, and promoted through concerted action of seemingly competitive Lewis acids, B(C6F5)(3), and a chiral Mg-PyBOX complex. Thus, a wide variety of beta-amino carbonyl compounds may be synthesized, with complete atom economy, through stereoselective reaction of an in situ-generated enantiomerically enriched Mg-enolate and an appropriate electrophile.

Asymmetric Synthesis of 2H-Azirines with a Tetrasubstituted Stereo-center by Enantioselective Ring Contraction of Isoxazoles

Highly strained 2H-azirines with a tetrasubstituted stereocenter were synthesized by the enantioselective isomerization of isoxazoles with a chiral diene-rhodium catalyst system. The effect of ligands and the coordination behavior support the proposed catalytic cycle in which the coordination site is fixed in favor of efficient enantiodiscrimination by a bulky substituent of the ligand. In silico studies also support the existence of a rhodium-imido complex as a key intermediate for enantiodiscrimination.

Nonpeptidal compounds from the insect Polyphaga plancyi and their biological evaluation

Five new nitrogen-containing compounds (1-3, 5, and 6), two compounds which was firstly isolated from natural origin (7 and 10), along with six known ones, were isolated from the ethanol extract of the whole bodies of Polyphaga plancyi. The structures of the new compounds including their absolute configurations at stereogenic centers were assigned on the basis of spectroscopic analyses and computational methods. Racemic 10 was separated by chiral HPLC. Biological activities of these isolates against extracellular matrix components in rat renal proximal tubular cells, EV71, COX-2, ROCK2, JAK3, and tuberculosis were evaluated. Importantly, 8 was found to be a selective Smad3 phosphorylation inhibitor.

Interconnection of sulfides and sulfoxides in medicinal chemistry

Aromatic heterocycles with basic nitrogen atoms as well as carboxylic acid derivatives are the dominating chemical space in the universe of drug-like molecules. These established and exceedingly evaluated structural motifs have to be combined with elements of diversity in order to chart less well-explored galaxies of chemical space and to be able to tackle seemingly undruggable targets. Flat scaffolds should be replaced by shapely molecular cores. In this context, it has been unheeded that phenyl rings in diaryl sulfides are less co-planar than in ethers and that the metabolic interconnection of sulfides and sulfoxides offers advantages that are unalike from the chemistry of amines and N-oxides in the CHN-O world. Moreover, sigma-hole potentials increase with the polarizability of the atom N < P < O < S and do not only play a role in long-time overlooked halogen bonds. Examples for lambda(2), lambda(4), and lambda(6) S-based functionalities related to improved solubility, reduced drug resistance, linkers in drug conjugates, drug-targeting to parasites, and as basis for drug monitoring in sports are given and discussed.

Cobalt-Catalyzed Asymmetric Hydrogenation of C=N Bonds Enabled by Assisted Coordination and Nonbonding Interactions

An efficient cobalt-catalyzed asymmetric hydrogenation of C=N bonds has been realized. Chiral hydrazines were obtained in high yields and with excellent enantioselectivities (95-98 % ee). The hydrogenation went smoothly at up to 2000 substrate/catalyst and on a gram scale. The success of this reaction relies on the presence of an NHBz group in the substrates, with the reactivity and enantioselectivity improved by an assisted coordination to the cobalt atom and a nonbonding interaction with the ligand. Furthermore, this reaction has practical applications for the synthesis of several useful chiral nitrogen-containing compounds.

Iridium-catalyzed Asymmetric Hydrogenation of Polycyclic Pyrrolo/Indolo[1,2-a]quinoxalines and Phenanthridines

Owing to the dehydrogenative rearomatization of hydrogenation product and poisoning effect of nitrogen atom, asymmetric hydrogenation of polycyclic nitrogen-containing heteroaromatics is still a great challenge. Herein, through insitu protection of hydrogenation products with acetic anhydride to inhibit rearomatization and poisoning effect, a novel iridium-catalyzed enantioselective hydrogenation of polycyclic nitrogen-containing heteroaromatics – pyrrolo/indolo[1,2-a]quinoxalines and phenanthridines – has been successfully developed, providing a facile access to chiral dihydropyrrolo/indolo[1,2-a]quinoxalines and dihydrophenanthridines with up to 98% ee. The strategy features broad substrate scope, easy operation and potential medicinal application.

Synthesis of Saxitoxin and Its Derivatives

The chiral synthesis of (+)-saxitoxin and its derivatives is described. Two consecutive carbon-nitrogen bonds at C-5 and C-6 in saxitoxin were effectively installed by the sequential Overman rearrangement of an allylic vicinal diol derived from d-malic acid. The bicyclic guanidine unit was constructed by the intramolecular aminal formation of an acyclic bis-guanidine derivative possessing a ketone carbonyl at C-4. From the bicyclic aminal intermediate, (+)-saxitoxin, (+)-decarbamoyl-beta-saxitoxinol [(+)-dc-beta-saxitoxinol], and the unnatural skeletal isomer, (-)-iso-dc-saxitoxinol, were synthesized.
