Abstract

NEW MATERIAL:A compound of formula I: (m is 1 or 2; n' and n" are o or 1).
EXAMPLE: 5-Oxo-2,3,6,7,8,9-hexahydro-5H-thiazolo[3,2-b]isoquinoline-1,1-dioxide.
USE: Analgesics and antiphlogistics.
PROCESS: A compound of formula II: (A is COOH or CN; B is OH or lower alkoxy group; however, B is OH when A is COOH) is reacted with a compound of formula III in an organic solvent to give a novel compound of formula IV, which is oxidized in an organic acid, e.g. acetic acid, under heating to form the compound of formula I. A 10W40% hydrogen peroxide is preferably used as the oxidizing agent.
