Abstract
Procedure for obtaining new dioxolane-2-carboxylic acids of the formula ** (See formula) ** where R1 and R2, which may be the same or different, represent hydrogen or halogen atoms, alkyl or alkoxy radical, R3 represents a hydrogen atom, an alkyl radical, an aryl radical or aralkyl radical, the aromatic rings thereof they may optionally be substituted by halogen atoms, lower alkyl or alkoxy moieties, X represents a group -CH2- or an -OCH2 group, whose oxygen atom is linked to the phenyl moiety and n represents an integer from 0 to 3 , as well as its alkaline or alkaline earth salts, characterized by reacting a diol of the formula ** (See formula) ** wherein R1, R2 and X have the indicated meanings, with a compound of the formula ** (See formula) ** where R3 and n have the meanings indicated above and Y represents a carboxyl, carbalkoxy or nitrile group, or an acetal or ketal thereof, preferably in the presence of a water or alcohol separating medium and preferably at temperatures between 80º and 160º C , and, of forming a compound of the formula ** (See formula) ** where R1, R2, R3, X and n have the meanings given above and Y represents a carbalkoxy or nitrile group, then saponifying it, preferably by alkaline route, and optionally converting the obtained compound of the formula I to a salt optionally into a salt alkaline or alkaline earth.
