Article abstract of DOI:10.1021/jo00002a029

A facile synthesis of the tricyclic enone 3 was completed; since 3 was an intermediate in a previous synthesis of (+/-)-dendrobine (1), this achievement constitutes a formal total synthesis of the racemic title alkaloid.The key strategic element of the ap
