Regio- and stereo-specificity of nucleophilic attack on steroidal π-allylpalladium complexes

Abstract

Reaction of α- and β-1–3-η-type steroidal π-allylpalladium complexes with AcOK yielded products resulting from trans-attack on the side opposite to the co-ordinated palladium, while reaction of steroidal olefins with PdCl2CuCl2-AcOK/AcOH afforded products arising from cis-attack.
