                                摘要:
                                Regioselective reaction of lithium dieneand triene-diolates 1 and 2 with o-diphenylphosphinyl hydroxylamine affords unsaturated alpha-amino acids 3 and 4.  Addition to DEAD leads selectively to gamma-hydrazino unsaturated acids 5 and 6.
