Abstract

A convenient and green method for the straightforward synthesis of β-amidovinyl sulfones has been described from enamides, high-valent iodine (III) dicarboxylates and DABCO-(SO₂)₂ under the irradiation of blue LEDs in the catalysis of 4CzIPN. The mild and metal-free reaction conditions make this protocol as an alternative strategy for the synthesis of β-amidovinyl sulfones.

在4CzIPN的催化下，在蓝色led的照射下，以烯酰胺、高价碘（III）二羧酸盐和DABCO-(SO2)2为原料，简便、绿色地合成了β-氨基酰胺基砜。温和且无金属的反应条件使该方案成为合成β-酰胺基砜的替代策略。
