We report efficient stereoselective and high yielding syntheses of each of the four enantiomers of phenylcyclopentanes bearing a quaternary center and a E-propenyl chain on the adjacent carbon that involves intramolecular allylic substitution reactions. In complement to its synthetic value, this process models the SN’ reaction and allows prediction of its stereochemical outcome.
我们报告了苯基环戊烷的四种对映异构体中的每一种的有效立体选择性和高产合成,这些对映异构体在相邻的碳上具有季中心和 E-丙烯基链,涉及分子内烯丙基取代反应。作为其合成价值的补充,该过程模拟了 SN' 反应并允许预测其立体化学结果。
