In the presence of zinc dust (1.5-2.0 equiv) and LiCl (1.5-2.0 equiv), various benzylic chlorides bearing functional groups (iodide, cyanide, ester, ketone) are smoothly converted at 25 degrees C to the corresponding zinc reagents without homo-coupling (<5%). The utility of these benzylic zinc reagents is demonstrated by a short synthesis of papaverine.
在锌粉(1.5-2.0当量)和LiCl(1.5-2.0当量)的存在下,各种带有官能团(碘,氰化物,酯,酮)的苄基氯在25摄氏度下平稳转化为相应的锌试剂,而不会-耦合(<5%)。这些罂粟碱的短合成证明了这些苄基锌试剂的实用性。
