Diastereoselective titanium-catalysed epoxidation reactions of acyclic homoallylic alcohols are presented. The results are compared to the stereochemical outcome obtained by the application of the commonly used vanadium catalyst, VO(acac)(2). The key role of the syn-bis-homoallylic carbamate group in obtaining high yields and reversed diastereoselectivities in the titanium-catalysed reactions is discussed. (C) 2002 Elsevier Science Ltd.
