Disilyloxydienes (2a-c) were easily obtained by treatment of stable sulfur yliders (1a-c) with chlorotrimethylsilane in the presence of triethylamine. Cycloaddition reaction of these dienes with some dienophiles was carried out.
在存在三乙胺的情况下,通过用三甲基氯硅烷处理稳定的硫代亚胺(1a-c),可以很容易地获得二烯(2a-c)。这些二烯与一些二烯亲核试剂发生环加成反应。
