- All these polyenes are highly unstable in the presence of light at room temperature
- IR spectra were run on a Perkin–Elmer model 681 and FT-IR spectrometers. 1H NMR spectra were recorded on Varian (300 MHz) and Brucker (300 MHz) spectrometers using CDCl3 with TMS as internal standard. Mass spectra were obtained on a Shimadzu QP-1000 mass spectrometer at 70 eV. UV spectra were recorded on Perkin–Elmer Lambda UV/VIS spectrometer. Silica gel (100–200 mesh) was used for column chromatography
