Conjugate addition of cyanide and allyl nucleophiles to S-(+)-carvone followed by annulation with methyl vinyl ketone gave the substituted decalones 2 and 3 stereoselectively. Both decalones were transformed into (−)-Ambrox®via modification of the sidechain, methylation, conversion of the isopropenyl group and cyclization.
将氰化物和烯丙基亲核试剂共轭添加到S-(+)-香芹酮中,然后与甲基乙烯基酮环化,得到立体选择性的取代的十碳杂萘2和3。既decalones转化到( - ) -艾姆罗克斯®经由侧链,甲基化,转换的异丙烯基和环化的修饰。
