An efficient, practical and regioselective synthesis of (E)-alkenylphosphine oxides has been developed starting from alkenes under copper catalysis and 4-HO-TEMPOH oxidation. Preliminary mechanistic studies clearly reveal that a phosphinoyl radical is involved in this process. Moreover, this method features mild reaction conditions, good functional group tolerance, and excellent regioselectivity and
在铜催化和 4-HO-TEMPOH 氧化下,以烯烃为原料,开发了一种高效、实用和区域选择性合成 ( E )-烯基氧化膦的方法。初步的机理研究清楚地表明膦酰基自由基参与了这一过程。此外,该方法具有反应条件温和、官能团耐受性好、区域选择性优良等特点,有望有效用于药物分子骨架的后期功能化。该反应将为合成复杂的含磷生物活性分子创造机会。
