9,10-dihydroanthracene-2-alkanoic acid derivative

Abstract

Abstract NEW MATERIAL:9,10-Dihydroanthracene-2-alkanoic acids of formula I (Y is C= O or CH 2 ; R 1 is H or lower alkyl), and their salts, esters and amide derivatives. EXAMPLE: Methyl antraquinon-2-ylacetate. USE: Analgesic antiinflammatory agents. Especially, having little digestive troubles. PROCESS: For example, dibenz [b, e] oxepine-2-alkanoic acid of formula II, or their salts, esters or amide derivatives are treated with an alkali, to obtain the compounds I wherein Y is C=O, and, further, these compounds are reduced, to obtain other compounds I where in Y is CH 2 .
