Abstract
A process for the preparation of cyclopentenones, of the general formula ** (See formula) ** wherein R1 represents hydrogen or an alkyl radical and R2 represents an alkyl, alkenyl, aryl or aralkyl radical or a saturated or unsaturated cycloaliphatic radical, characterized in that it consists in reacting a compound of the general formula ** (See formula) ** wherein R1 has the meaning set forth above, with a secondary amine of the general formula ** (See formula) ** where A and B represent organic radicals, which can be linked together to form a cyclic system, to form an enamine of the general formula ** (See formula) ** where A, B and R1 have the meaning stated above, in reacting the enamine with a donor agent of R2, so as to form a tertiary alcohol of the general formula ** (See formula) ** where R1 and R2 have the meaning stated above, and in dehydrating said tertiary alcohol, to form a cyclopentenone of the general formula I above.
