| titleOfInvention | Process for preparing dibenzothione derivatives |
| abstract | The present invention relates to a novel process for the preparation of dibenzothiepyne derivatives. Specifically, α-halogenation of alkyl esters of 5-propionyl-2-phenylthio phenyl acetic acid is used to convert them into cyclic acetals using diol compounds and to form Lewis. The acid-catalyzed transition reaction yielded a dicarboxylic acid 5- (1-carboxyl) -2-phenylthiophenylacetic acid compound, followed by a cyclization reaction to give 2- (10,11-dihydro) -10-oxo dibenzo [b, f] thipin-2-yl) propionic acid.n n n [Formula 1]n n n n n n n n Dibenzothiene, preparation method, yield, anti-inflammatory, analgesic |
