In the diiodomethane–copper methylenation of 3- and 4-methoxycyclopentenes and 3-methoxycyclohexene, the cis isomers of the cyclopropane derivatives predominated over the corresponding trans isomers, the trans isomer of cyclopropane derivatives being predominantly obtained from 3-methoxycyclooctene.
在3-和4-甲氧基环戊烯和3-甲氧基环己烯的二碘甲烷-铜亚甲基化反应中,环丙烷衍生物的顺式异构体比相应的反式异构体占优势,环丙烷衍生物的反式异构体主要从3-甲氧基环辛烯中获得。
