Abstract

A simple total synthesis of herqulines B and C is reported, modeled on the reductive biosynthesis reported previously by other researchers. Commencing from tyrosine, these alkaloids were fashioned through a dimerization, macrocyclization, and four consecutive reductions. Emerging from these studies are strategic insights on the synthesis of these strained alkaloids, as well as mild conditions for the exhaustive reduction of diketopiperizines.
