endo/exo and regioselectivity have been investigated. In all cases cycloaddition reactions exhibited full regio- and endo-stereoselectivity. The obtained cycloadducts are new polycyclic allylic sulfides carrying much structural and stereochemical informations. Work on transformation of the adducts, mainly to the corresponding new 1,3-dienes and aromatic compounds, is also presented.
描述了热和路易斯酸催化的(Z)-1,2-二杂取代的1,3-二烯与各种亲二烯体的环加成反应。两个内/外和区域选择性进行了研究。在所有情况下,环加成反应均表现出完全的区域和内部立体选择性。所获得的环加合物是新的多环烯丙基硫化物,具有许多结构和立体化学信息。还介绍了加合物转化的工作,主要是转化为相应的新的1,3-二烯和芳族化合物。
