Multifunctional group compounds, 2-acyl-3-sulfonamidobut-2-enoates, are efficiently constructed using solid calcium carbide as an alkyne source through the simultaneous formation of two bonds in one step. The salient features of this protocol are the use of an inexpensive, abundant, and easy-to-use alkyne source as a substitute for flammable and explosive gaseous acetylene, low-cost catalyst, mild conditions
使用固体碳化钙作为炔烃源,通过一步同时形成两个键,有效地构建了多官能团化合物 2-酰基-3-磺酰胺基丁-2-烯酸酯。该方案的显着特点是采用廉价、丰富、易于使用的炔烃源替代易燃易爆的气态乙炔,催化剂成本低廉,条件温和,底物范围广,立体选择性高,收率满意。 ,并且操作简单。该方法还可以扩展到克级。
