Preparation of piperidinylcyclopentylheptenoic acid derivatives |
| abstract |
A process is described for the preparation of a compound of formula (2) ##STR1## (wherein R is a C 1-6 alkyl or a C 7-20 aralkyl group) and the salts thereof, which comprises reducing a compound of formula (3) ##STR2## (or a salt thereof), using a reducing system comprising borohydride ions and metal ions selected from lanthanide ions, alkaline earth metal ions or yttrium ions in solution. The reduction system may be provided by a borohydride (e.g. NaBH 4 ) and a metal salt (e.g. CeCl 3 ). n The ester (2) may then if desired be hydrolyzed to give the parent acid. |
