A simple one-step synthesis of 1,2,4-triazole derivatives is provided by a copper-catalyzed oxidative coupling reaction under an atmosphere of air. The process should consist of sequential. N-C and N-N bond-forming copper-catalyzed oxidative coupling reactions. Starting materials and the copper catalyst are readily available and inexpensive. A wide range of functional groups are tolerated to achieve chemical diversity.

The syntheses and the pregnancy-terminating activity relationships of compounds 5a-n are reported. Compounds 5b and 5l are found to be more potent than DL-111-a known drug having effective pregnancy-terminating activity in vitro. Further research shows compounds 5b and 5l have the same activity as DL-111 in vivo. We also found an exciting result that they have excellent anti-implantation activity after oral administration.

PhI(OCOCF<sub>3</sub>)<sub>2</sub>-Mediated Intramolecular Oxidative N–N Bond Formation: Metal-Free Synthesis of 1,2,4-Triazolo[1,5-<i>a</i>]pyridines
readily synthesized from N-(pyridin-2-yl)benzimidamides via phenyliodine bis(trifluoroacetate)-mediated intramolecular annulation. This novel strategy allows for the convenient construction of a 1,2,4-triazolo[1,5-a]pyridine skeleton through direct metal-free oxidative N–N bond formation, featuring a short reaction time and high reaction yields.
具有生物学重要性的1,2,4-三唑并[1,5- a ]吡啶很容易通过苯基碘双(三氟乙酸)介导的分子内环化反应从N-(吡啶-2-基)苯甲酰胺酰胺合成。这种新颖的策略允许通过直接形成无金属的氧化性N–N键来方便地构建1,2,4-三唑并[1,5- a ]吡啶骨架,其反应时间短且反应产率高。
