a ]isoquinolines 8a,b, 9a,b and 10a were synthesized by the reactions of homocalycotomine 7 with appropriate dichlorophosphorus derivatives, such as phenylphosphonic dichloride, bis(2-chloroethyl)phosphonic dichloride or phosphoryl chloride. In spite of the blocking effect of the connecting isoquinoline ring system, the oxazaphosphorinane moiety exists as a chair–twist equilibrium, where the conformer
摘要 1,3,2-Oxazaphosphorino[4,3-a]异喹啉8a,b,9a,b 和10a 是由homocalycotomine 7 与适当的二氯磷衍生物如苯膦二氯化物、双(2-氯乙基)膦酸反应合成的。二氯化物或磷酰氯。尽管连接异喹啉环系统具有封闭效应,但氧氮杂膦烷部分仍以椅-扭转平衡的形式存在,其中构象异构体的比例强烈依赖于 P-4 构型和取代基的立体电子特性。
