A facile and short synthesis of a series of quinazolino[1,4]benzodiazepine alkaloids, including asperlicin C, circumdatin H and some analogues, is reported utilizing coupling of readily available [1,4]benzodiazepine with 2-nitrobenzoyl chlorides, followed by a reductive Nheterocyclization.
据报道,利用现成的 [1,4] 苯二氮卓类与 2-硝基苯甲酰氯的偶联,可以简便且快速地合成一系列喹唑啉并 [1,4] 苯二氮卓类生物碱,包括阿斯帕林 C、环菌素 H 和一些类似物。还原性杂环化。
