Indirect substitution by a cyclopentyl group in 80% yield may be accomplished by hydrogenation of the unsaturated ester formed by condensation of cyclopentanone and cyanoacetic ester (Knoevenagel reaction) (method 37). Alkaline hydrolysis followed by thermal decarboxylation gives cyclopentylacetic acid (82%). ... [Pg.666]
