Abstract: Abstract A highly reactive intermediate N-sulfonyl acetylketenimine was generated from an ynone-participated CuAAC/ring-opening method. Its unique structure allowed it to react with aryl carboxylic acids to give N-aroylsulfonamides via a novel Mumm-type rearrangement. read more here.

DOI: 10.1080/00397911.2023.2204193
Abstract: Abstract An I2-mediated N–N coupling reaction has been described for oxidation cyclization of 2,2,2-trifluoro-N-(1-iminoethyl)-N′-arylacetimidamide to synthesis of novel 3-methyl-1-aryl-5-(trifluoromethyl)-1H-1,2,4-triazole derivatives under mild conditions with excellent yield without need to any purification. This procedure doesn’t have… read more here.

DOI: 10.3762/bjoc.18.143
Abstract: A convergent strategy for the synthesis of leustroducsins and phoslactomycins has been designed, relying on the synthesis and the coupling of three main fragments. The central fragment was synthesized via a regio-and stereoselective nitroso Diels–Alder… read more here.
