synthesis of the methyl-ionone isomers 6–9 is described. The enantiomers of the γ-isomers 8 and 9 are prepared by enzyme-mediated resolution of the corresponding 4-hydroxy derivatives followed by reductive elimination of the hydroxy group. The absolute configuration of the latter compound is determined by chemical correlation with the known α-isomers. Since all the isomers obtained are components of the
甲基紫罗兰酮异构体的区域选择性合成6 - 9进行说明。γ-异构体8和9的对映异构体是通过酶介导的相应的4-羟基衍生物的拆分,然后还原性消除羟基而制备的。后一种化合物的绝对构型通过与已知的α-异构体的化学相关性确定。由于所有获得的异构体下Iralia的商品名人工紫罗兰增味剂的成分®,它们的气味性质是由调香师的专业评估。
