Two sequential asymmetric bicyclopropanation reactions were used to prepare (1R,3S,4R,6S,7S,9R,10S,12R)-quatercyclopropyl-1,12-dimethanol and (1S,3R,4R,6S,7S,9R,10R,12S)-quatercyclopropyl-1,12-dimethanol.
采用两个连续的不对称双环丙烷化反应,合成了(1R,3S,4R,6S,7S,9R,10S,12R)-四环丙基-1,12-二甲醇和(1S,3R,4R,6S,7S,9R,10R,12S)-四环丙基-1,12-二甲醇。
