The first enantioselective synthesis of (-)-physostigmine (1), a potent cholinesterase-inhibiting alkaloid from Physostigma venenosum Balf., has been accomplished using (S)-(-)-benzyl 2, 3-epoxypropyl ether (5) as a chiral synthon.
以(S)-(-)-苄基 2,3-环氧丙基醚(5)为手性合成物,首次完成了(-)-physostigmine(1)的对映选择性合成,(-)-physostigmine(1)是从 Physostigma venenosum Balf.中提取的一种强效胆碱酯酶抑制生物碱。
