efficient, and versatile one-pot cascade reaction of diverse Gewald's aminothiophenes, 2-hydroxy-4-oxobut-2-enoic acid, and derivatives of cyanoacetic acid catalyzed by Et3N is presented. It enables direct synthesis of diverse 1-(2-oxoethylidene)-2-oxothieno[3,2-e]pyrrolo[1,2-a]pyrimidine in good to excellent yields. The reaction exhibits a broad substrate scope and also presents an opportunity for further
from the cycloaddition of acyl(quinoxalinyl)ketenes with carbodiimides. The described reaction represents the first example of a divergent synthesis based on acyl(quinoxalinyl)ketenes providing (quinoxalin-2-yl)-1,3-oxazines or pyrimido[1,6-a]quinoxalines depending on the type of the acyl substituent in the ketenes. The key reactants, acyl(quinoxalinyl)ketenes, are generated in situ via the thermal decarbonylation
从酰基(喹喔啉基)乙烯酮与碳二亚胺的环加成反应,已经开发出一种简便的合成方法,可用于两种独特的基于喹喔啉的杂环骨架。所描述的反应代表了基于酰基(喹喔啉基)乙烯酮,根据酰基取代基的类型提供(喹喔啉-2-基)-1,3-恶嗪或嘧啶并[1,6- a ]喹喔啉的发散合成的第一个例子在烯酮中。关键反应物酰基(喹喔啉基)烯酮是通过容易获得的吡咯并喹喔啉氧代衍生物的热脱羰作用而原位生成的。所提出的面向多样性的合成提供了从廉价试剂中轻松获取骨架多样的药学上有趣的基于喹喔啉的杂环文库的途径。

A new efficient and versatile one-pot three-component synthesis of substitutedpyrrolo[1,2-]thieno[3,2-e]pyrimidine derivatives has been developed. It is based on a multistep cascade reaction from 2-aminothiophenes and 2-hydroxy-4-oxobut-2-enoic acids, and derivatives of cyanoacetic acid catalyzed by diisopropylethylamine. As a result, novel pyrrolo[1,2-]thieno[3,2-]pyrimidine derivatives (21 compounds)
