Abstract

A short and highly diastereoselective synthesis of the amphibian alkaloid pumiliotoxin C is described, based on the preparation of an octahydroquinoline derivative through a four-component reaction. The route proceeds in 66% overall yield from 1,3-cyclohexanedione and includes two hydrogenation steps, whose stereochemical outcome was controlled vianitrogen acylation.
