✦ Synopsis

Conjugate additions and conjugate ad$ition-alkylations proceed with very high stereoselectivity to a,&unsaturated acyls of n -CpFe(CO)(PPh ). 2

Oxidative cleavage of the products provides high yields of organic acid derivatives (es ers, B-lactams) with almost complete control of relative stereochemistry.
