Sulfonate derivs. (I; R1=C1-4 alkyl, C2-6 alkoxyalkyl, cycloalkyl, substituted C1-12 alkyl, C1-4 alkoxy, halogen, OH carboxy, acetamino, NO2; R2=C1-15 alkyl, C2-15 alkenyl, C2-5 cyclialkylether; halogen, C1-4 alkoxy, acyloxy, carbobenzoxyamino, C2-5 cyclicalkenylether; n=0-6), used as anti-infla-mmatories, immunity regulators, antistyptics, were prepd. by the reaction of R1SO3H and XCH2CO(CH2)nR2(X; halogen). Thus, 1.2g 1-dia30-2-pentanon was dissolved in 50ml enter, added to 2, 3g C6H5SO3HH2O slowly. The reactant was stirred from N2 gas to releasing. A column chromatography was isolated to give 2g 2-oxopentylbenzensulfonate.
