Efficient synthesis of highly enantiopure β-lactam derivatives from biocatalytic transformations of amides and nitriles

Catalyzed by Rhodococcus erythropolis AJ270, a nitrile hydratase and amidase containing microbial strain, under mild conditions, kinetic resolution of racemic amides provides an efficient and scalable route to highly enantioenriched R-4-carboxymethyl-β-la

An approach to carbapenems from α,β-unsaturated sugar lactones

Conjugate addition-rearrangement of N-substituted hydroxylamines to α,β-unsaturated D-lactones provides a short and effective route to 3-substituted isoxazolidin-5-ones. These compounds were converted into 4-substituted azetidin-2-ones via a two-step proc

HIGHLY EFFICIENT OXAZOLONE-DERIVED REAGENTS FOR BETA-LACTAM FORMATION FROM BETA-AMINO ACIDS

Based on a unique leaving ability of 2-oxazolone moiety, highly efficient reagents have been developed for the formation of β-lactam compounds from β-amino acids including a facile preparation of penam, a basic skeleton of penicillins.

SYNTHETIC STUDIES ON OPTICALLY ACTIVE β-LACTAMS. CHIRAL SYNTHESIS OF CARBAPENAM RING SYSTEM STARTING FROM L-ASPARTIC ACID

Benzyl (3R,5R)-1-carba-2-oxopenam-3-carboxylate (12), a useful synthon for β-lactams having carbapenem ring system, was synthesized in optically pure state starting from L-aspartic acid.
