The base-induced tandem-coupling/cyclization reactions of various α-sulfonyl acetamide derivatives A with methyl acrylate differentiated between two different pathways to form α-sulfonyl analogs of glutarimides B and 2-hydroxycyclohexenecarboxylic acid derivatives C in different ratios. The reaction of α-sulfonyl acetamide dianion with methyl acrylate depended on three factors: the stability of the
各种α-磺酰基乙酰胺衍生物A与丙烯酸甲酯的碱诱导的串联偶联/环化反应在两种不同的途径之间进行区分,从而以不同的比例形成戊二酰亚胺B和2-羟基环己烯羧酸衍生物C的α-磺酰基类似物。α-磺酰基乙酰胺二价阴离子与丙烯酸甲酯的反应取决于三个因素:二价阴离子的稳定性,丙烯酸甲酯的浓度以及磺酰和酰胺取代基的结构。通过改变反应条件,我们有效地控制了环加成反应以合成所需的产物,每种产物均具有潜在的生物学活性。提出了反应的闭环机理。
