Abstract

The synthesis of a carbovir analogue, (+/-)-homocarbovir (3) was achieved from norbornadiene (4) in seven steps and 27% overall yield. This route involves a Meinwald-type rearrangement, an acid-hydrolysis of N-tosyl bicyclic enamine 5, and a Pd(0)-catalyzed coupling reaction.

摘要

从降冰片二烯(4)出发,通过七步反应,以27%的总收率实现了卡波韦类似物(±)-高卡波韦(3)的合成。该路线涉及迈因瓦尔德型重排、N-对甲苯磺酰基双环烯胺5的酸水解以及钯(0)催化的偶联反应。
