Zinc triflate catalyzed facile synthesis of novel 1,2,4-triazolinone derivatives using 3-Arylsydnone as synthon

A series of novel tetrazoles (4a-k) and thiazolidinones (6a-k) appended to 2-Aryl-1,2,4-triazolin-3-ones were efficiently synthesized from 3-Arylsydnones (1a-k) in excellent yields using Zinc triflate as catalyst.

Transformation of the sydnone ring into oxadiazolinones. A convenient one-pot synthesis of 3-aryl-5-methyl-1,3,4-oxadiazolin-2-ones from 3- arylsydnones and their antimicrobial activity

3-Arylsydnones (Ia-u) have been converted into the corresponding 3-aryl- 5-methyl-1,3,4-oxadiazolin-2-ones (IIIa-u) by a single-step reaction with bromine in acetic anhydride. In the preliminary screening of all these compounds, the halogen-substituted de
