Abstract Translated from German Neue tetra-substituierte Benzolderivate der Formel worin X Sauerstoff, Schwefel oder Hydroxyimino; Y Methylen oder Imino; R 1 Hydroxy, Phosphonooxy, Glycosyloxy, aciliertes Glycosyloxy, Acyloxy oder nieder-Alkoxycarbonyloxy; R 2 nieder-Alkoxy, nieder-Alkenyloxy oder nieder-Alkylthio; R 3 nieder-Alkoxy; R 4 nieder-Alkyl, p-nieder-Alkoxybenzoyl oder substituiertes oder unsubstituiertes Phenyl, Benzyl, Pyridylmethyl, Fürturyl, Tetrahydrofurfuryl, Thenyl, Tetrahydrothenyl, Pyrrolylmethyl, Pyrrolinylmethyl oder Pyrrolidinylmethyl darstellt, mit der Bedingung, daß X nicht Methylen ist, wenn R 4 Alkyl, Phenyl, substituiertes Phenyl, Benzyl oder p-Hydroxybenzyl ist und mit der weiteren Bedingung, daß R 2 und R 3 voneinander verschieden sind, wenn R 4 p-Methoxybenzyl und Y Methylen ist, und pharmazeutisch anwendbare Salze davon, sind antiviral wirksam. Sie können nach mehreren Verfahrensweisen hergestellt werden. New tetra-substituted benzene derivatives of the formula wherein X is oxygen, sulfur or hydroxyimino; Y is methylene or imino; R 1 is hydroxy, phosphonooxy, glycosyloxy, acidified glycosyloxy, acyloxy or lower alkoxycarbonyloxy; R 2 lower alkoxy, lower alkenyloxy or lower alkylthio; R 3 lower alkoxy; R 4 represents lower alkyl, p-lower alkoxybenzoyl or substituted or unsubstituted phenyl, benzyl, pyridylmethyl, fururyl, tetrahydrofurfuryl, thenyl, tetrahydrothenyl, pyrrolylmethyl, pyrrolinylmethyl or pyrrolidinylmethyl, with the condition that X is not methyl, when R 4 is not methylene , Phenyl, substituted phenyl, benzyl or p-hydroxybenzyl and with the further condition that R 2 and R 3 are different from each other when R 4 is p-methoxybenzyl and Y is methylene, and pharmaceutically acceptable salts thereof, have an antiviral effect.
