摘要：

The beta-(trifluoromethyl)vinyl sulfides on treatment with n-BuLi/TMEDA at -78 degrees C were readily lithiated at an a-position of the Sulfanyl group, and the generated (beta-trifluoromethyl-alpha-sulfanylvinyl anions were reacted with a variety of electrophiles to give the corresponding beta-trifluoromethyl-alpha-functionalized-vinyl sulfides 4aa-4aq in good to excellent yields. The reactivity of some products has been examined. The palladium-catalysed cross-coupling reaction as well as homo-coupling reaction of Oaf provided the corresponding products in good yields, respectively. The Diels-Alder reaction of cyclic dienes and 14 derived from 4ao provided the desired six-membered cyclic products with high endo-trifluoromethyl group selectivity. (C) 2009 Elsevier Ltd.
