dihydrocinchonine and dihydrocinchonidine. The potential of the method is illustrated by the asymmetric synthesis of (+)-podocarp-8(14)-ene-13-one (13) and of (−)-Wy-16,225 (10), a bridged aminotetralin with potent analgesic properties.
已经评估了通过CPTC在α-芳基取代的酮,酯和内酯的烷基化反应中(烷基卤化物和烯酮)的不对称诱导。所用的催化剂是辛可宁,辛可尼定,二氢辛可宁和二氢辛可宁的N-(对-三氟甲基)苄基衍生物的溴化物。该方法的潜力通过不对称合成(+)-罗汉松8(14)-烯13-一(13)和(-)-Wy-16,225(10)(一种具有强效镇痛作用的桥连氨基四氢萘)进行了说明。特性。
