β-hydroxy ketone O-benzyl oximes with lithium aluminum hydride in the presence of sodium or potassium methoxide afforded the corresponding syn-β-amino alcohols in highly stereoselective manner. A lythraceae alkaloid, lasubine II, was synthesized stereoselectively by applying this method.
在甲醇钠或甲醇钾存在下用氢化铝锂还原 β-羟基酮 O-苄基肟,以高度立体选择性的方式提供相应的顺-β-氨基醇。应用该方法立体选择性地合成了lythraceae生物碱,lasubine II。
