Dirhodium(ll) catalysts possessing chiral pyrrolidone or oxazolidinone ligands provide moderate enantioconfrol (up to 80% ee) in carbon-hydrogen insertion reactions of N-alkyl-N-(tert -butyl)diazoacetamides; substituents at the P-position of the N-alkyl group control regioselectivity for p-and ylact
