Efficient New Approach for the Synthesis of N,N-Dialkylamino-1,2,4-triazoles
摘要:
A series of 3-N,N-dialkylamino-4,5-diaryl-1,2,4-triazoles were synthesized in high yield under mild reaction conditions by coupling functionalized arylmagnesiums with isothiocyanates and cyclization with Viehe's salts. No selective thionation reaction was required for the preparation of carbamoyl derivatives.
