Quantum chemical studies on some potentially tautomeric thiazolidinone derivatives and their thio and azo analogs

Abstract

The gas phase semi-empirically calculated relative stability and tautomeric equilibrium values revealed that 2C, 4C, and 5C hydroxy substituted thiazolidinone derivatives prefer oxo forms. The 2C, 4C, and 5C mercapto substituted derivatives also found to prefer the thione forms. On the contrary 2C, 4C, and 5C amino substituted derivatives were found to prefer amino forms. ©ARKAT USA, Inc.
