Abstract

NEW MATERIAL:Compounds of formula I (R1 is H, lower alkyl, or aryl; R2 is lower alkyl, aryl or aralkyl; n is 0, 1, or 2).
EXAMPLE: 3-Methylthiazolidine-4-one.
USE: They are useful as synthetic intermediates for medicines and expected, as it is, as chemical reagents, analgesics, antiflammatory agents.
PREPARATION: Formaldehyde or paraformaldehyde is made to act on an amidethiol derivative of formula II in an appropriate solvent under an acidic condition using hydrochloric or p-toluenesulfonic acid at room temperature to 150°C for 1W6 hr to yield the objective compound of formula I.
