Racemic endo-4-acetoxybicyclo[3.2.1]oct-2-ene furnishes enantiopure (+)-bicyclo[3.2.1]oct-3-en-2-one and its dihydro derivative leaving enantiopure (+)-endo-4-acetoxybicyclo[3.2.1]oct-2-ene in a phosphate buffer solution in the presence of a lipase (Candida antarctica) and palladium(II) chloride. Utilizing the products, a diastereocontrolled route to some cyclopentanoid monoterpenes has been established
外消旋内-4- acetoxybicyclo [3.2.1]辛-2-烯配料对映纯的(+) -双环[3.2.1]辛-3-烯-2-酮及其衍生物二氢离开对映纯的(+) -内型-4脂肪酶(南极假丝酵母)和氯化钯(II)的存在下,在磷酸盐缓冲溶液中加入-乙酰氧基双环[3.2.1]辛-2-烯。利用这些产物,已经建立了对一些环戊烷单萜的非对映控制途径。
