Cyclization of the unsaturated sulfoxides 18b,18c under Pummerer conditions provided the six-membered products 20a and 21a, whereas base-catalyzed cyclization of the stereoisomeric epoxysulfones 16a,16b and 17a,17b led exclusively to the five-membered compounds 12a,12b and 15a,15b. The reaction 18b,18c → 20a,21a has been used to prepare the trans-decaline derivative 24 starting from the dimethylcyclohexenone
在Pummerer条件下不饱和亚砜18b,18c的环化提供了六元产物20a和21a,而立体异构环氧砜16a,16b和17a,17b的碱催化环化仅导致了五元化合物12a,12b和15a。 ,15b。反应18b,18c→20a,21a已用于从二甲基环己烯酮6制备反癸烷衍生物24。
