Syntheses of Optical Isomers of Cyano-(6-phenoxy-2-pyridyl)methyl trans-3-(4-tert-Butylphenyl)-2, 2-dimethylcyclopropanecarboxylate and Their Biological Activities

Studies on Phenylcyclopropanecarboxylates (Part 2)

Abstract

Four optically active isomers of cyano-(6-phenoxy-2-pyridyl)methyl trans-3-(4-t-butylphenyl)-2, 2-dimethylcyclopropanecarboxylate were prepared. Their acaricidal and insecticidal activities were found to depend largely on the absolute configuration of the acid moiety but not on that of the alcohol moiety. cis-Isomer of the ester did not have any acaricidal activity.
