The geometry of dienes obtained from 2,3-substituted sulfolenes bearing a 3-carboxyl derivative is dependent on the nature of the 3-carboxy group and on the functionality of the 2-substituent. These factors therefore have a crucial influence on the stereoselectivity of subsequent Diels-Alder reactions. (C) 1997 Published by Elsevier Science Ltd.
