areneselenosulfonates add readily to allenes in a highly regiospecific fashion (eq 3) to give . Oxidation of the PhSe group in to PhSe(O) is followed by [2,3]-sigmatropic rearrangement to and hydrolysis of to the β-arylsulfonyl-substituted allylic alcohol , thereby providing a simple, high-yield route to these interesting compounds.
-苯基芳烯
硒代
磺酸盐易于以高度区域特异性的方式(等式3)加到亚丙基中,得到。将PhSe基氧化为PhSe(O),然后进行[2,3]σ重排为β-芳基磺酰基取代的烯丙基醇,然后
水解为β-芳基磺酰基取代的烯丙基醇,从而为这些有趣的化合物提供了一种简单的高收率途径。
