    Abstract: Disclosed is a process for the preparation of a 5-hydroxy-3-ketoester derivative of the formula: in which R represents an alkyl group, an alkenyl group, an alkynyl group, an aryl group or a heterocyclic group, and R represents an alkyl group or an aryl group, which comprises causing the reaction of an aldehyde compound of the formula R CHO in which R has the meanings as defined above and diketene in the presence of a metal compound selected from a titanium or aluminum compound having at least one group of -OR in which R represents an alkyl group or an aryl group. Further, a process for the preparation of an optically active substance of the 5-hydroxy-3-ketoester derivative causing the reaction of the above compounds in the presence of the metal compound and optically active Schiff base or a complex compound obtained by reacting the metal compound with the optically active Schiff base, also is disclosed.
