Abstract R-(+)-pulegone (1) is transformed to (R)-5-methyl-2-(phenylsulfinyl)cyclohexanone (5) (65%, 3 steps). Sulfoxide 5 is converted to R-(-)-3,5-dimethylcyclohex-2-en-1-one (4) (53%, 4 steps) and S-(+)-4 (26%, 3 steps).
摘要 R-(+)-pulegone (1) 转化为 (R)-5-methyl-2-(phenylsulfinyl)cyclohexanone (5)(65%,3 个步骤)。亚砜 5 转化为 R-(-)-3,5-二甲基环己-2-en-1-one (4)(53%,4 步)和 S-(+)-4(26%,3 步)。
