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.

design, chemical synthesis, and biologicalevaluation of a novel family of delta opioid receptor (DOR) antagonists containing a 1,2,4-triazole core structure that are structurally distinct from other known opioid receptor active ligands. Among those delta antagonists sharing this core structure, 8 exhibited strong binding affinity (K(i) = 50 nM) for the DOR and appreciable selectivity for delta over
