Cyanoacetic acid derivatives are the starting materials for a plethora of multicomponent reaction (MCR) scaffolds. Here we describe valuable general protocols for the synthesis of arrays of 2-aminothiophene-3-carboxamides from cyanoacetamides, aldehydes or ketones, and sulfur via a Gewald-3CR variation. In many cases the reactions involve a very convenient work up by simple precipitation in water and filtration
氰基乙酸衍生物是大量多组分反应(MCR)支架的起始材料。在这里,我们描述了通过Gewald-3CR变异体从氰基乙酰胺,醛或酮和硫合成2-氨基噻吩-3-羧酰胺阵列的有价值的通用协议。在许多情况下,通过在水中简单沉淀和过滤,反应涉及非常方便的后处理。描述了40多种新产品。我们预见到我们的方案及其产生的衍生物对于极大地扩展氰基乙酰胺衍生物的MCR支架空间将变得非常有价值。
