A suitably functionalized tricyclic adduct,Containing the Ne common A,B,E rings found in calyciphylline B-type alkaloids was obtained in nine linear steps. The key transformation features an efficient one-pot sequence of intramolecular Vilsmeier-Haack cyclization and azomethine ylide 1,3-dipolar cycloaddition in which three cycles, three new carbon-carbon bonds, and three stereocenters are formed, one being fully substituted. This work also demonstrates the first use of a chiral, nonracemic cyclic enol ether as an internal carbon nucleophile.
