A short and efficient synthesis of the title compounds is described. (S)-(−)-β-Cuparenone was prepared in 31% yield from p-tolualdehyde and mesityl oxide in eight steps. Absolute stereochemistry was established by means of a diastereoselective cyclopropanation using (R,R)-hydrobenzoin as a recoverable auxiliary.
描述了标题化合物的短而有效的合成。(S)-(-)-β-Cuparenone由对甲苯甲醛和异丁烯氧化物经八步制备,收率为31%。借助于(R,R)-氢安息香作为可回收助剂的非对映选择性环丙烷化建立了绝对立体化学。
