A series alpha-hydroxyalkyldithiolanes were reacted with a mixture of triphenylphosphine, diethyl azodicarboxylate and hydrazoic acid to give 2-azido-1,4-dithianes stereoselectively. Reduction of the azido group to an amine resulted in racemisation. (C) 1998 Elsevier Science Ltd. All rights reserved.
