All-trans-5-demethylretinal and its 5-2H, 7-2H and 5,7-2H2 isotopomers have been synthesized by means of a new and simple scheme. Using photochemistry, the 9-, 11- and 13-cis, as well as the 9,13- and 11,13-di-cis isomers, were obtained. The structures were established by means of 1H NMR spectroscopy.
