biosynthetic studies on the unique cyclopropane alkaloid cyclizidine (1). The stereochemistry of the ring-opening to the homoallylic alcohol (4) was investigated by synthesis of chirally deuteriated (3) followed by 1Hn.m.r.spectroscopy of the ring-opened product with a chiral shift reagent. It was found to proceed with inversion of configuration.
环丙基苯基甲醇(3)是通过在独特的环丙烷生物碱环联吡啶(1)的生物合成研究过程中降解而获得的。通过合成手性氘代(3),然后用手性位移试剂对开环产物进行1 H nmr光谱研究,研究了均丙醇(4)开环的立体化学。发现可以进行配置反转。
