The alkaloids of <i>Lycopodium cernuum</i> L. III. The synthesis of dihydrodeoxyepiallocernuine

Abstract

The synthesis of dihydrodeoxyepiallocernuine (IV) is described, as is the synthesis of the tricyclic compound XVI, a degradation product of lycocernuine. These syntheses provide a rigorous proof of the constitution of cernuine and lycocernuine, and also provide strong support for the stereochemistry assigned to these alkaloids.
