制备对映体纯相转移催化剂3a-j、4a-j、5、8a-j、9a、B、10 a、B，其代表生物碱基本结构的变化。这些在三个对映选择性模型反应中进行了测试。结果表明，喹啉侧臂和奎宁环核是PT催化剂的重要特征。(C)1999爱思唯尔科技有限公司。保留所有权利。
Enantiopure phase transfer catalysts 3a-j, 4a-j, 5, 8a-j, 9a,b, 10a,b were prepared which represent changes in the fundamental structure of the alkaloids. These were tested in three enantioselective model reactions. It turned out that both the quinoline group carrying side arm and the quinuclidine core are important features of PT catalysts for highly enantioselective reactions. (C) 1999 Elsevier Science Ltd.
