The well-defined complex [Tpm*,BrCu(NCMe)]BF4 efficiently catalyses the [3+2] cycloaddition between alkynes and N-sulfonylazides under mild conditions, with conversions comparable to others obtained with in situ generated catalytic systems previously described for this transformation.

The transformation of N-sulfonyl-1,2,3-triazoles via insertion/rearrangement is achieved using 2-hydroxybenzimidazole or 2-alkoxybenzothiazole over 3 mol % Rh2(Oct)4 for the synthesis of α-((1H-benzo[d]imidazol-2-yl)amino) ketones or (Z)-2-alkoxy-2-phenylethenamines. This regio- and stereoselective reaction proceeds undermildconditions, is tolerant of functional groups, and has a broad substrate
N-磺酰基-1,2,3-三唑通过插入/重排的转化是使用2-羟基苯并咪唑或2-烷氧基苯并噻唑在3 mol % Rh 2 (Oct) 4上合成α-((1 H-苯并[ d ]imidazol-2-yl)amino) 酮或 ( Z )-2-alkoxy-2-phenylethenamines。这种区域选择性和立体选择性反应在温和的条件下进行,对官能团具有耐受性,并且具有广泛的底物范围。值得注意的是,虽然一般的铑催化反应涉及烯丙基乙烯基醚的 sigmatropic 重排,但本合成方法防止了由于苯并咪唑基团的重排,允许获得 ( Z)-烯烃。

Eight- and 9-membered dioxazocines and dioxazonines are readily synthesized starting from N-sulfonyl-1,2,3-triazoles in a single-step procedure. A perfect regioselectivity and generally good yields (up to 92%) are obtained under dirhodium catalysis using 1,3-dioxolane and 1,3-dioxane as solvents and reagents.
