- TLC (EtOAc/Petroleum ether 1:1) plate results were interpreted by UV light and/or developed by spray of 10% ammonium phosphomolybdic acid in ethanl or 10% concentrated sulphuric acid in ethanol followed by heating with air-gun for a few seconds. 3-Methoxy-2,5(10)-dienes (1a°c) and 5(10)-en-3-ones (2a°c) were not observable under UV light at 254nm and 365nm but observable after the treatment mentioned above. The UV spectra of the products (2a°c) all showed absorption maximum at ca. 204nm (95% EtOH) due to tetra substituted olefin 5(10)-ene chromophore. The conjugated 4-en-3-ones had characteristic absorption maximun at ca. 240nm (95% EtOH).18—19
