## Abstract The UV, spectra and the polarizationof the individual absorption bands have been measured for tropone, 2,7‐dimethyl‐4, 5‐benzotropone and 2, 7‐dimethyl‐4, 5‐naphtotropone. The positions, relative intensities and polarizations of these bands predicted by a simplified version of the PPP‐m
An efficient and stereodefined process is described for the first preparation of a new prenyl-benzoylfuranone type sesquiterpenoid, (±)-3-(2,4-dihydroxybenzoyl)-4,5-dimethyl-5-(4,8-dimethyl-3(E),7(E)-nonadien-1-yl)tetrahydro-2-furanone. The synthetic strategy is based on nucleophilic addition of org
