Cyclic sulfamidates as lactam precursors. An efficient asymmetric synthesis of (-)-aphanorphine

A short and efficient enantioselective synthesis of (-)-aphanorphine is described based on the use of a cyclic sulfamidate to provide a suitably functionalised lactam that allows for construction of the tricyclic 3-benzazepine scaffold. The Royal Society
