A three-step synthesis of (R)-(+)-4-methylcyclohex-2-ene-1-one (1) from (R)-(+)-pulegone (3), proceeding in 44% overall yield, is described. The sequence comprises vinyl triflate formation, site-selective ozonolysis, and reduction. The route requires only one chromatographic purification and provides a convenient method to access multigram quantities of (R)-(+)-4-methylcyclohex-2-ene-1-one (1).
由(R)-(+)-Pulegone(3)进行的三步合成(R)-(+)-4-甲基环己-2-烯-1-一(1)的总产率为44%描述。该序列包括三氟甲磺酸乙烯酯的形成,位点选择性臭氧分解和还原。该路线仅需进行一次色谱纯化,即可提供一种便捷的方法来访问多克数量的(R)-(+)-4-甲基环己-2-烯-1-酮(1)。
