  Efficient Synthesis of N-2-Aryl-1,2,3-Triazole Fluorophores via Post-Triazole Arylation

  摘要：

  Efficient post-triazole regloselective N-2 arylation was developed from C-4, C-5 disubstituted-1,2,3-NH-triazoles. Three different approaches had been investigated, including SNAr, Cu(I) catalyzed aryl amidation and Cu(II) mediated boronic acid coupling. The N-2-aryl triazoles were successfully synthesized with excellent yields. The structures were characterized by X-ray crystallography and some N-2-triazole products gave strong fluorescence with various emission controlled by the C-5 groups.

  One Step Cascade Synthesis of 4,5-Disubstituted-1,2,3-(NH)-Triazoles

  摘要：

  A Lewis base-catalyzed three-component cascade reaction was developed for the synthesis of 4,5-disubstituted-1,2,3-(NH)-triazoles. More than 25 new (NH)-triazoles were prepared in good to excellent yields under mild conditions. The availability of the C-4 vinyl group allows easy conversion into other triazole derivatives.

  The Mitsunobu reaction was used in the preparation of chiral triazole derivatives. The reactions gave good to excellent yields with large substrate scope. Complete stereochemistry inversion was obtained, making this strategy one practical approach for the synthesis of enantiomeric enriched triazole analogous.

  Mitsunobu反应用于制备手性三唑衍生物。该反应在较大的底物范围内产生了良好的优异产率。获得了完全的立体化学转化，使得该策略成为合成对映体富集的三唑类似物的一种实用方法。

  日期：2009.7

  Au(I) catalyzed 1,2,3-triazole addition to non-activated alkyne was reported. A large group of substituted NH-1,2,3-triazoles were suitable for this transformation along with both internal and terminal alkynes. The N-1 and N-2 vinyl substituted 1,2,3-triazoles were prepared in up to 98% yield with as low as 0.2% catalyst loading, thereby providing a new protocol for the synthesis of potentially biological-active vinyl-triazole building blocks.
