Cyanomethylenetributylphosphorane was shown to mediate the dehydrocyclization of diols and amino alcohols to give the corresponding 6-membered O- and N-heterocycles in 90% or better yields. Using the reaction as a key step, (+)-alpha-skytanthine, a unique mono terpene alkaloid was synthesized stereoselectively. Copyright (C) 1996 Elsevier Science Ltd
