Abstract

The challenging vicinal quaternary and tertiary stereocenters of the 5, 10b- ethanophenanthridine skeleton are created in a single step utilizing intramolecular [3+ 2]- cycloaddition of nonstabilized azomethine ylide as the key step. The application of the chemistry is demonstrated by synthesizing (±)-maritidine.
