Disclosed is a method for producing an optically active 3-methylcyclopentadecan-1-one which is characterized in that 2-cyclopentadecen-1-one is subjected to a 1,4-conjugate addition reaction of a methyl group by using a methylated organic metal in the presence of a copper catalyst, an enol anion scavenger and a specific optically active phosphoramidite for obtaining an optically active 3-methyl-1-cyclopentadecene derivative, and then the thus-obtained 3-methyl-1-cyclopentadecene derivative is subjected to a solvolysis.
本发明公开了一种生产具有光学活性的 3-甲基环十五烯-1-酮的方法,其特征在于:在铜催化剂存在下,使用甲基化的有机金属,使 2-环十五烯-1-酮与一个甲基发生 1,4-共轭加成反应、烯阴离子清除剂和特定光学活性亚磷酰胺,以获得光学活性 3-甲基-1-环 十五烯衍生物,然后将由此获得的 3-甲基-1-环十五烯衍生物进行溶解。
