Abstract
In connection with our investigation on the structure-activity relationships of the American cockroach sex pheromone mimic, (+)-trans-verbenyl acetate, a number of alcohols having 6,6-dimethylbicyclo[3, 1. l]heptane skeleton were synthesized, and measured their PMR spectra in the presence of the shift reagent, Eu(dpm)3. The induced shifts of the 6, 6-gem-dimethyl protons and α-proton at the C–7 guided us to distinction between cis- and trans-alcohol. The configuration of secondary methyl groups was discussed from the induced shift values of the methyl protons.
