3,5-Dihydroxypentanoic ester derivatives of formula (I):
(wherein:
A represents an alkylene group which is optionally substituted by one or more alkyl groups, or an alkenylene group;
Z represents a substituted or unsubstituted aryl or aryloxy group; and
R represents a C1 - C4 alkyl group)
may be prepared by reacting a dianion of an acetoacetic ester with an aldehyde of formula Z-A-CHO (wherein A and Z are as defined above) and then reducing the resulting compound. These 3,5-dihydroxypentanoic ester derivatives have antihyperlipaemic activity and are thus valuable pharmaceuticals.
