shown in the cyclopropanation reaction of 1. The conversion of 1 into 7,7-dimethylbicyclo[4.1.0]heptan-1,2-diols (±)-2 and (±)-3 represents an important transformation in a synthetic strategy towards phorbol derivatives. TBDMS=tert-butyldimethylsilyl.
在1的环丙烷化反应中显示了卤代和烷基卡宾的非对映体互补性(分别为路径a和b)。1转化为7,7-二甲基双环[4.1.0]庚烷-1,2-二醇(±)-图2和(±)-3表示合成策略向佛波醇衍生物的重要转变。TBDMS =叔丁基二甲基甲硅烷基。
