reactions, giving the corresponding 2,2-disubstituted-3-cyclohexenone derivatives in a completely regioselective manner. This newly developed methodology has been successfully applied towards the total synthesis, in racemic form, of the marine natural product nanaimoal.
发现4-氰基-2-环己烯酮易于还原烷基化反应,以完全区域选择性的方式得到相应的2,2-二取代-3-环己烯酮衍生物。这种新开发的方法已成功地以消旋形式完全合成了海洋天然产物纳那莫尔。
