, p. 4346 - 4354 (2021)
A multicomponent reaction of triazoloketones, primary amines, and 4-nitrophenyl azide was developed for the synthesis of hitherto unknown angularly fused/linear bitriazoles. The two-stage mechanism was well proven by the isolation of the intermediate. Thi
DBU catalyzed metal free synthesis of fused 1,2,3-triazoles through [3+2] cycloaddition of aryl azides with activated cyclic C–H acids

DBU catalyzed synthesis of fused 1,2,3-triazoles by [3+2] cycloaddition of aryl azides with activated cyclic C–H acids such as dimedone, cyclohexane-1,3-dione, 5-methylcyclohexane-1,3-dione, and 2-hydroxynaphthalene-1,4-dione in PEG-400 has been reported

A practical and efficient method for the synthesis of 1,2,3-triazoles via the cycloaddition reaction of azides and CH-acids in the presence of 1,1,3,3-tetramethylguanidine (TMG) in ethanol at 30 C has been reported. The simple experimental procedure, shor
DIAZO GROUP TRANSFER AND/OR TRIAZOLE FORMATION IN THE REACTION OF TOLUENE-4-SULPHONYL OR 4-NITROPHENYL AZIDE WITH α-METHYLENE β-DICARBONYL COMPOUNDS IN HEXAMETHYLPHOSPHORIC TRIAMIDE

In hexamethylphosphoric triamide, toluene-4-sulphonyl azide generally performs smooth diazo group transfer to β-dicarbonyl compounds, whereas 4-nitrophenyl azide can exhibit diazo transfer reaction with malonates and cyclic β-diones but leads to triazole formation with acyclic β-diones and β-keto esters.
