Electrosynthesis of 2-(1,3,4-Oxadiazol-2-yl)aniline Derivatives with Isatins as Amino-Attached C1 Sources.

An intramolecular decarboxylative coupling reaction for the construction of 2-(1,3,4-oxadiazol-2-yl)aniline derivatives was developed from readily available isatins and hydrazides by virtue of electrochemistry. In this reaction, isatins were employed as amino-attached C1 sources, providing a variety of 2-(1,3,4-oxadiazol-2-yl)aniline derivatives with moderate to good yields.
