Visible-Light-Induced photoredox aerobic coupling of sulfonium ylides and amines leading to E-selective formation of 2-amino-2-butene-1,4-diones

A novel visible-light-induced photoredox three-component aerobic coupling reaction of sulfoxonium ylides and amines is reported. The protocol provides a general strategy for the construction of structurally valuable highly functionalized 2-amino-2-butene-1,4-dione...
