Artificial visual pigment formation was studied by using 8-methyl-substituted retinals in an effort to understand the effect that alkyl substitution of the chromophore sidechain has on the visual cycle. The stereoselectivesynthesis of the 9-cis and 11-cis isomers of 8-methylretinal, as well as the 5-demethylated analogues is also described. The key bond formations consist of a thallium-accelerated
