reported a new synthesis of amides from esters and amines under microwave irradiation, offering much higher yields than those achieved with conventional heating [1]. We have now extended these studies to the ring closure of neat iminoesters I2, I3 and I4-I6 to give five- and six-membered ring lactams L5, L6 and larger lactams L7-L9 (where I means imine and L means lactam), respectively, under both classical
我们以前曾报道过在微波辐射下由酯和胺合成酰胺的新方法,其产率要比传统加热方法高得多[1]。现在,我们已经将这些研究扩展到纯亚氨基酯I2,I3和I4-I6的闭环,得到五元和六元环内酰胺L5,L6和较大的内酰胺L7-L9(其中,我的意思是亚胺,L的意思是内酰胺),分别在经典加热条件和微波辐射下。
