✦ Synopsis

Abstract

Ibogamine (11b) was synthesized starting from the vinyl sulfone 3. Addition of organocuprate reagents to 3 furnished 2a–d with high stereoselectivity. Only products from the syn addition of the cuprate reagents could be detected. Functional group transformations provided 7a,b the key intermediates for the synthesis of (±)‐21‐noribogamine (11a) and (±)‐ibogamine (11b).
