Two methods for the synthesis of norbornane‐fused indanes via palladium‐catalyzed three‐component reactions of iodoarenes, norbornenes, and CH2Br2 or α‐diazoesters have been developed. In the reactions, three C−C bonds were constructed and a wide range of norbornane‐fused indanes could be synthesized. The reactions with α‐diazoesters proceeded with a high degree of diastereoselectivity and indanes
已经开发了两种通过钯催化的碘代芳烃,降冰片烯和CH 2 Br 2或α-重氮酸酯的三组分反应合成降冰片烷稠合的茚满的方法。在反应中,构建了三个CC键,可以合成各种降冰片烷稠合的茚满。与α-重氮酸酯的反应具有高度的非对映选择性,并形成了带有全碳四元中心的茚满。在1,4-二氢-1,4-环氧萘的反应中获得的产物可以转化为芴,提供了另一种获取芴衍生物的方法。
