Synthesis of the Putative Structure of (±)-Amarbellisine

Abstract

The title compound was synthesized mainly by palladium catalytic coupling, cyclopropyl ring-opening rearrangement, epoxidation, Swern oxidation, demethanol reactions, and selective reduction. This synthesis was achieved in 16 steps with 9.7% overall yield. Unfortunately, the published spectroscopic data do not match with those of our synthetic compound.
