Abstract

Geometric isomers of all-trans-9-demethyl-, -13-demethyl- and -9,13-bisdemethylretinal were prepared. The 360 MHz 1H NMR spectra of 13 geometric isomers of these three demethylated retinal systems have been measured. The chemical shift and coupling constant values in each case allowed an unambiguous assignment of the structure of each compound.
