Exceedingly facile single step expedient protocols based on the versatility and reactivity of corresponding intermediates : [2-(dimethylaminomethylene) ketone] (5) and chalcone (6), derived from 2-(p-acetyl phenoxyl) substituted analogue of pyrrolo[2,1-c][1,4]-benzodiazepine (4), have been developed to provide an easy installation of the pyrimidine based privileged templates at 2-position of pyrrolo[2,1-c][1,4]-benzodiazepine through a p-phenoxyl spacer, by utilizing the synthetic strategy depicted in schemes-1and2.
基于相应中间体的多功能性和反应性,开发了非常简便的单步骤便捷协议:利用从2-(p-乙酰基苯氧基)取代的吡咯并[2,1-c][1,4]-苯并二氮杂环(4)衍生的[2-(二甲氨基甲基)酮](5)和查尔酮(6),通过利用示例1和示例2中所示的合成策略,通过p-苯氧基间隔在吡咯并[2,1-c][1,4]-苯并二氮杂环的2位提供了易于安装嘧啶基特权模板的方法。
