A synthesis of the enantiomerically pure right-hand part (2) of an insect antifeedant, azadirachtin, is described. Reduction with baker's yeast was demonstrated to be efficient for kinetic resolution of racemic diketone (4) to give 3 of ∼75% e.e., from which was derived 2 in 11 steps.
描述了昆虫拒食剂印za素的对映体纯的右手部分(2)的合成。已证明用面包酵母还原可有效拆分外消旋二酮(4),得到约75%ee中的3 ee,它是在11个步骤中由2衍生而来的。
