Abstract The azidophenyl 6, 7-epoxygeranyl ethers rac-4c and rac-4d and the azidobenzoate rac-6 were synthesized. p-Azidophenyl 6, 7-epoxygeranyl ether (rac-4c) shows a high affinity to the juvenile hormone binding protein of the migratory locust, Locusta migratoria. Fast photolysis is observed upon irradiation at 254 nm and at 300 nm. It is proposed that rac-4c is useful as a new reagent for the study of juvenile hormone binding ...
