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

Protecting group migration in the chemistry of 1-t-butyldimethylsilyl-4-hydroxymethyl-2-azetidinone

The alkoxide anion derived from 1-t-butyldimethylsilyl-4-hydroxymethyl-2-azetidinone (1) rearranged at -78°C into amide anion by N-O migration of the silyl protecting group. The occurrence of this intermediate was proved by quenching with benzyl bromide and phenethyl chloroformate, giving respectively N-benzyl (4) and N-(phenethyloxycarbonyl) (6) derivatives of 4-(t-butyldimethylsilyloxy)methyl-2-azetidinone.

Heterocyclic compounds containing an alkoxycarbonyl and a substituted methyl group

The invention relates to new heterocyclic compound containing an alkoxycarbonyl and a substituted methyl group a process for the preparation of these and analogeous compound and pharmaceutical compositions containing them. More particularly, the invention concerns compounds of the general formula (IVa) STR1 wherein R' is hydrogen, 2-ethoxycarbonylethyl, aryl or a group suitable for a temporary protection of amides and Y' represents a group of the formula --COOZ or --CH2 M, in which Z is lower alkyl and M is hydroxyl, halogen, cyano or a group of the formula --O--SO2 R2, in which R2 is lower alkyl or aryl, with the proviso that if R' is phenyl, Y' cannot stand for the group --COOC2 H5. The invention further relates to a process for the preparation of compounds of the general formula (IV) STR2 in which R and Y are identical with R' and Y', respectively, except the proviso. According to a further aspect of the invention there are provided pharmaceutical compositions, first of all with antihypoxic activity, comprising compounds of the general formula (IVa) as active ingredient.
