✦ Synopsis

Gas-phase eliminations of 4-substituted-2-alkoxythiazoline-5-ones have been studied. These compounds eliminate via a six-membered transition state to produce 4-substituted-thiazolidine-2,5-diones. These eliminations are unimolecular first-order reactions. Utilization of this thermolysis reaction in the synthesis of new 4-substituted-thiazolidine-2,5-diones is considered. Additional mechanistic information was ob-

tained bv comparing the kinetic data for thermal elimination reactions of these compounds with that of Iethoxythiazob. 0 I996 John Wiley & Sons, Inc.
