between (+)-(R)-p-tolyl vinyl sulphoxide and cyclopentadiene gives four separable diastereoisomers. The two most abundant were transformed by a two-step procedure into the two enantiomers of dehydronorcamphor (bicyclo[2,2,1]hept-5-en-one) possessing very high enantiomeric purity.
(+)-(R)-对甲苯基乙烯基亚砜与环戊二烯之间的狄尔斯-阿尔德反应,得到四种可分离的非对映异构体。通过两步操作将两个最丰富的对映体转化为具有非常高对映体纯度的脱氢降樟脑的两个对映异构体(双环[2,2,1]庚-5-烯一)。
