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
