Abstract
A procedure for the preparation of new disubstituted xanthone-2-carboxylic acid derivatives, represented by the formula: ** (See formula) ** and its pharmaceutically acceptable, non-toxic esters, amides and salts, where the R1 groups may be the same or different and are independently selected from lower alkyl and lower alkoxy, the process of which consists of: 1) condensing a phenol o, p-disubstituted with a 1,3-di-carboalkoxy-4-halobenzene in the presence of cuprous oxide to give the corresponding 1,3-dicarboalkoxy-4- (phenyloxy o, p-di-substituted) benzene, hydrolyze the latter in basic medium to give the corresponding 1,3-dicarboxy-4- (phenyloxy or, p-di-substituted) benzene and cycle the latter to give the corresponding 5,7-disubstituted xanthone-2-carboxylic acid, where the two substituents are independently selected from alkyl and alkoxy; and 2) optionally converting a product from step 1) to its pharmaceutically acceptable, non-toxic esters, amides and salts.
