acid esters, and α,β-enoic acid amides can be efficiently achieved by the use of [RhCl(cod)]2 catalyst. A high diastereoselectivity (95% yield, 90% de) was obtained through the reaction of α,β-enoic acid amide derived from Oppolzer'ssultam and 2-butenoyl chloride, while the use of Evans' chiral oxazolidinone as a chiral auxiliary in place of Oppolzer'ssultam gave a poor diastereoselectivity (98% yield
