摘　　要：报道了一个O_(2)促进下五元环烯胺的C—H亚胺化反应.在微波辐射下,季酮酸或1,3-环戊二酮衍生的烯胺酮、芳酮醛水合物和芳胺三组分参与的无金属催化反应进展顺利,以良好的产率和完全的立体选择性得到了一系列α-烯胺基-α-芳酰基亚胺衍生物.在该反应过程中,空气充当绿色氧化剂,水是唯一的副产物.An O_(2)-enabled C—H imination of five-membered cyclic enamines is reported.Metal-free catalytic threecomponent reactions of tetronic acid-or 1,3-cyclopentanedione-derived enaminones with arylglyoxals and arylamines worked well under microwave irradiation,furnishing a series ofα-enamino-α-aroyl imines with good yields and complete stereoselectivity.In this reaction process,air serves as the green oxidant with water as the sole byproduct.

关 键 词：三组分 区域选择性亚胺化 微波辐射
