cyclopropane n.【藥學】環丙烷〔麻醉劑〕。

cyclops

A new convenient synthesis of a series of polyfluoroalkyl substituted cyclopropane derivatives was achieved by the reaction of polyfluoroalkyl iodides with diethyl allylmalonate in the presence of sodium dithionite in 45 % ~ 55 % yields 摘要以連二亞硫酸鈉為引發劑,烯丙基丙二酸二乙酯與多氟烷基碘代烷在溫和條件下反應,方便地得到一系列多氟烷基取代的環丙烷衍生物,產率45 % ~ 55 % 。

Cyclopropane rings are included within larger systems, such as triterpenes . 三元環包含在較大的環系統中,像三萜類中。

A variety of cyclopropanes are thus produced in good yield . 從而以高收率得到帶各種環丙烷。

Treatment with butyllithium gave rise to cyclopropanes . 用丁基鋰處理,即得到環丙烷。
