An efficient and new approach has been developed to synthesize bis(β,β'-dialkoxy carbonyl) derivatives through the reaction between N-tosylaziridines and malonate esters under ambient air using tBuOK in DMSO solvent. A plausible reaction pathway has been predicted. Control experiments suggested that the reactions proceed through the formation of α-aminoketones. This reaction offers a broad substrate scope, metal-free synthesis, excellent regioselectivity, easily accessible reactants, and simple operation. A gram-scale synthesis demonstrates the potential applications of the present method.

在无金属条件下通过氮丙啶的氧化裂解串联双(β,β'-二烷氧基羰基)化合物的新方法。

通过在DMSO溶剂中使用tBuOK在环境空气下,N-甲苯磺酰氮丙啶与丙二酸酯之间的反应,开发了一种有效的新方法来合成双(β,β'-二烷氧基羰基)衍生物。已经预测到可能的反应途径。对照实验表明,反应是通过形成α-氨基酮来进行的。该反应提供了广泛的底物范围,无金属合成,出色的区域选择性,易于获得的反应物以及简单的操作。克级合成证明了本方法的潜在应用。
