Bicyclo[3.1.0]hexanones bearing an aryl group on the cyclopropane ring are stereoselectively prepared on reaction of the corresponding benzylidene sulfuranes with cyclopentenones. The synthesis of compounds bearing geminal phenyl and methyl groups on the cyclopropane ring proves to be possible because the corresponding sulfonium salt, inaccessible until now, is now available.
在相应的亚苄基硫烷与环戊烯酮反应后,立体选择性地制备在环丙烷环上带有芳基的双环[3.1.0]己酮。事实证明,合成合成在环丙烷环上带有双苯基和甲基双键的化合物是可行的,因为目前尚无法获得相应的sulf盐。
