synthesize α-sulfonylamino ketones through the reaction between terminal alkynes and sulfonamides under ambient air using PIDA (diacetoxy iodobenzene). A library of α-sulfonylamino ketone derivatives having a variety of substituents has been synthesized. A plausible reaction pathway has been predicted. This reaction offers a broad substrate scope, metal-free synthesis, excellent regioselectivity, easily
已经开发出一种新颖有效的方法,通过在环境空气下使用PIDA(二乙酰氧基碘苯)使末端炔烃与磺酰胺之间的反应合成α-磺酰基氨基酮。已经合成了具有多种取代基的α-磺酰基氨基酮衍生物的文库。已经预测到可能的反应途径。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在环境空气下的室温反应条件,并且操作简单。克级合成证明了本方法的潜在应用。另外,在没有磺酰胺的情况下,我们还合成了α-乙酰氧基酮。
