Diazene-directed modular synthesis is described for the preparation Csp2-Csp3 and Csp3-Csp3 linkages where one or more stereogenic quaternary carbon centers are formed. The disclosed methods are directed to the preparation of compounds of Formula (I), or a pharmaceutically acceptable salt, tautomer or stereoisomer thereof, from compounds of Formula (II):
wherein R1-R5 and q are as defined independently for each occurrence herein. A wide variety of compounds can be accessed in this manner, including oligocyclotryptamines, where the stereochemistry of each subunit is beneficially secured before fragment coupling.
本发明描述了重氮定向模块化合成法制备 Csp2-Csp3 和 Csp3-Csp3 连接,其中形成了一个或多个立体源季碳中心。所公开的方法用于从式(II)化合物制备式(I)化合物或其药学上可接受的盐、同分异构体或立体异构体:
其中 R1-R5 和 q 在每次出现时均独立定义。通过这种方式可以获得多种化合物,包括低聚环
色胺,在片段偶联之前,每个亚基的立体
化学结构都能得到有效保证。
