The first synthesis of nostoclide I (1a) and II (1b) has been accomplished in a concise, fully regio- and stereocontrolled manner by sequential 2,3,4-trisubstitution of butenolide (6) using 2-furanolates as key intermediates.
通过使用2-呋喃酸酯作为关键中间体,依次进行丁烯内酯(6)的2,3,4-三取代,以简明,完全区域控制和立体控制的方式完成了诺古丁内酯I(1a)和II(1b)的首次合成。
