An efficient synthesis of the imine form of the pyrrolo[2,1-c][1,4]benzodiazepine ring system based on a new reductive cyclization procedure is described. The naturally occuring antibiotic DC-81(5c) and its 5-thio analogue (7c) have also been synthesized to illustrate the usefulness of this methodology.
描述了一种基于新的还原环化程序的吡咯并[2,1- c ] [1,4]苯并二氮杂ring环系统的亚胺形式的有效合成。还合成了天然存在的抗生素DC-81(5c)及其5-硫代类似物(7c),以说明该方法的有用性。
