  An Unexpected Diethyl Azodicarboxylate-Promoted Dehydrogenation of Tertiaryamine and Tandem Reaction with Sulfonyl Azide

  摘要：

  It is shown here for the first time that diethyl azodicarboxylate promotes dehydrogenation of tertiaryamines to afford enamines, which subsequently take place in tandem reactions with sulfonyl azides to give the N-sulfonyl amidine derivatives. A number of different substituted tertiaryamines and sulfonyl azides can successfully be coupled, and several functionalized groups are tolerated in this system. The reaction described here is mild, general, and efficient, thus providing an extremely preferable method for synthesis of a variety of N-sulfonyl amidine derivatives.

  sulfonyl azide as a nitrogen donor, a visible-light-enabled aerobic dealkylative imidation of tertiary and secondary amines involving C(sp3)–C(sp3) bond cleavage with moderate to excellent yields at room temperature is described. It has been demonstrated that this imidation could take place spontaneously upon visible-light irradiation, and could be facilitated considerably by a ruthenium photocatalyst

  使用磺酰叠氮化物作为氮供体，描述了一种在可见光下对叔胺和仲胺进行有氧脱烷基化酰亚胺化，涉及 C(sp 3 )–C(sp 3 ) 键断裂，在室温下具有中等至优异的产率。已经证明，这种酰亚胺化可以在可见光照射下自发发生，并且可以通过钌光催化剂和氧气大大促进。还提出了先前需氧光氧化还原途径的替代机制。
