  Metal-free, highly regioselective sulfonylation of NH-1,2,3-triazoles with sodium sulfinates and thiosulfonates

  摘要：

  A convenient and metal-free protocol for the highly regioselective sulfonylation of NH-1,2,3-triazoles is described. A range of readily accessible NH-1,2,3-triazoles were sulfonylated with various aryl sulfinates in the presence of molecular iodine. The scope was extended to thiosulfonates as an efficient sulfonylating agent and nitrochromene derived triazoles were also explored for selective N-sulfonylation. A variety of synthetically viable N-2-sulfonyl triazoles were obtained in moderate to high yields with excellent regioselectivities via N-S bond construction under mild reaction conditions.

  three‐component reaction of aromatic aldehydes, nitroalkanes, and sodium azide has been developed; this reaction sequence can be applied to a broad substrate scope and affords the corresponding 4‐aryl‐NH‐1,2,3‐triazoles in good to excellent yields. The milder reaction conditions and easier operation make this AlCl3‐catalyzed protocol more advantageous for the synthesis of 4‐aryl‐NH‐1,2,3‐triazoles.

  An efficient copper-catalyzed C–N bond formation by N–H/C–H cross-dehydrogenative coupling (CDC) between NH-1,2,3-triazoles and N,N-dialkylamides has been developed. The method provided N-amidoalkylated 1,2,3-triazoles with moderate to high yields, and the reactions showed high N2-selectivities when 4,5-disubstituted NH-1,2,3-triazoles served as the substrates.
