A FACILE SYNTHESIS OF THIAZOLIDIN-5-ONES AND THEIR STRUCTURAL ASSINGMENT
The reaction of 1,3-disubstituted thioureas (I) with α-halacyl halides (II) was found to afford thiazolidin-5-ones (IV) in 5percent sodium hydroxide-dichloromethane in the yields of 34-89percent.The structures of IV were discussed in details.
