A model study toward the total synthesis of (±)-scopadulin is described. Stereocontrolledsynthesis of the A/B ring system with desired functionalities was achieved by stereoselective cyanation of a bicyclic enone with Et2AlCN, diastereoselective construction of a quaternary carbon at C-4 with LDA-BOMCl, and conversion of the cyano group into a methyl group.

Treatment of primary aliphatic amines with KOH in diethylene glycol at 210 degrees C gives primary alcohols directly in good yields. A synthetic application to a model study of (+/-)-scopadulin is also described.[Graphics]
