The total synthesis of (−)-suaveoline

Abstract

A new synthesis of the indole alkaloid (−)-suaveoline from L-tryptophan is reported (overall yield ca. 14%). Key synthetic steps include a high yielding cis-specific Pictet–Spengler reaction, a one-pot Horner–Wadsworth–Emmons and alkylation procedure, a vinylogous Thorpe cyclisation and the direct formation of a 3,4,5-trisubstituted pyridine from a 1,5-dinitrile. The direct conversion of ajmaline to semi-synthetic suaveoline is also described.
