, p. 192 - 195 (2016)
[Figure not available: see fulltext.]Efficient synthesis of 1-arylsulfonyl-1,2,3-triazoles from easily available (Z)-arylvinyl bromides is described. The sequential reaction involves elimination of HBr from (Z)-arylvinyl bromides promoted by KOH and copper-catalyzed (3+2) cycloaddition reaction between the alkyne intermediates and sulfonyl azides.

The α-imino carbenes generating from 1-tosyl-1,2,3-triazoles have exhibited unique reactivities. A novel and efficient route for the construction of oxa-bridged 2,5-epoxy-1,4-benzoxazepines through a rhodium(II)-catalyzed tandem process of triazoles and salicylaldehydes has been developed. The oxazoles are obtained when 2-methanesulfonamidyl benzaldehyde is used instead of salicylaldehydes.
Efficient synthesis of N-arylsulfonyl-1,2,3-triazoles from 1,1-dibromo-2-arylethylenes
Xu, Wenjing,Zhang, Wensheng,Zhang, Fei
, p. 165 - 167 (2016/07/06)
N-arylsulfonyl-1,2,3-triazoles were synthesized from 1,1-dibromo-2-arylethylenes via a one-pot reaction involving the Cs2CO3-mediated dehydrobromination process of the dibromoalkenes to produce alkynes followed by the Cu(I)-catalyzed Huisgen cycloaddition of the alkyne intermediates with tosyl azide.
Facile synthesis of substituted 3-aminofurans through a tandem reaction of N-sulfonyl-1,2,3-triazoles with propargyl alcohols

, p. 3878 - 3882 (2016/06/01)
A relay catalysis strategy for substituted 3-aminofurans synthesis has been developed. This transformation involves a tandem reaction sequence through aza-vinyl-rhodium(ii) carbene O-H bond insertion, thermal propargyl-Claisen rearrangement and gold(i)-catalyzed intramolecular cyclization. More importantly, the current strategy employs simple feedstocks as starting materials, providing substituted 3-aminofurans in a highly efficient manner.
