In view of planned syntheses of target cyclobutane derivatives, a series of new 3-substituted bicyclobutanes was prepared from sulfones 1–7. Some novel addition reactions involving the central bond were then applied to several of the new compounds as well as to some previously described bicyclobutanes. These reactions include the additions of hydrazoic acid, of cyanocuprate reagents other than methyl
考虑到目标环丁烷衍生物的计划合成,从砜1–7制备了一系列新的3-取代的双环丁烷。然后将涉及中心键的一些新颖的加成反应应用于一些新化合物以及一些先前描述的双环丁烷。这些反应包括加入肼酸,除甲基试剂以外的氰基铜酸盐试剂和苯硒酚,以及添加苯硒基叠氮化物和溴化锂的单个例子。通过转化为环丁烷,环氧化和分子内碱诱导的环化反应,将几种3-烯丙基化的双环丁烷衍生物转化为1-(芳基磺酰基)双环[2.1.1]己烷。
