Abstract
Abstract Novel 3,3-dimethyl-2-(2''-oxo-3''-x-cyclopentylidenemethyl)-1cyclopropanecarboxylic acids of a cis or trans structure, in the form of racemic mixtures or optically active isomers of the formula WHEREIN X is selected from the group consisting of oxygen, sulfur and imino and R is selected from the group consisting of hydrogen, lower alkyl of one to six carbons, a radical of the formula WHEREIN Y3 is aryl such as phenyl, and a radical of the formula WHEREIN Z is alkenyl or alkadienyl such as allyl, butenyl and pentadienyl and their preparation and intermediates therefor.
