organozinc derivatives to Iron stabilized TMM-alcohols. These are decomplexed, under partial hydrogenation, by photolysis in acetic acid to give allylic and homoallylic isoprenoic alcohols. Starting from the optically active complex (+)-3, this allows a rapid synthesis of (R)-(-)-Ipsdienol of high ee.
甲酰基-TMM(铁)三羰基3以高非对映选择性与有机锌衍生物反应生成铁稳定的TMM醇。在部分氢化下,通过在乙酸中光解将它们分解,得到烯丙基和均烯丙基异戊二烯醇。从旋光配合物(+)- 3开始,可以快速合成高ee的(R)-(-)-伊潘二醇。
