Abstract
A new hexacyclic iboga-type indole alkaloid, voacangalactone (1), was isolated from Voacanga africana , and its structure including the absolute configuration was established by asymmetric total synthesis involving such key steps as the asymmetric Diels-Alder reaction using an aminodiene and the construction of an isoquinuclidine ring and an indole skeleton.
