A simple and practical synthesis of (R)-(−)-muscone was achieved by optical resolution of dl-muscone using tartaric acid derivatives. The acetalization of dl-muscone with N,N′-dibenzyl-l-tartaramide in the presence of Sc(OTf)3 and methyl orthoformate furnished a diastereomeric mixture of acetals, which were readily separated by simple recrystallization. Diastereomerically pure acetal was hydrolyzed
(R)-(-)- muscone的简单实用合成是通过使用
酒石酸衍
生物对dl- muscone进行光学拆分而实现的。在Sc(OTf)3和原
甲酸甲酯的存在下,用N,N'-二苄基-1-酒石酰胺对dl -muscone进行
缩醛化,得到了
缩醛的非对映异构体混合物,可以通过简单的重结晶将其分离。非对映体纯的
乙缩醛经
水解得到光学纯的
麝香酮,并回收了N,N′-二苄基-1-酒石酰胺。
