Abstract

A process for the preparation of new substituted acids, of the following general formula: ** (See formula) ** where ** (See formula) ** R can be closed on both ring A and ring B R '= alkyl group (C1 to C4) R''=R' o H characterized in that the chloromethyl derivative of the formula R is reacted with cyanide, and the corresponding nitrile is monoalkylated or dialkylane with consecutive saponification of the nitrile group, to form an acid.
