Abstract

NEW MATERIAL:Cyclopentane derivatives of fomula I (R1 is H, OH, lower alkoxy; A is protecting group for oxo and carbonyl).
EXAMPLE: 1,1'-ethylenedioxy-3,4-dimethoxycarbonylmethylcyclopentane.
USE: Synthetic intermediate of prostacycline (PGI2), which has activity inhibiting platelet coagulation.
PREPARATION: A compound of formula II is oxidized and, when necessary, the resulting carboxylic acid is esterified to produce the objective compound of formula I.
