Notizen: A new class of vitamin A analogs (retinoids) was synthesized containing a dimethylene bridge to maintain a 6-s-trans conformation of the terminal double bonds. The 1H and 13C NMR spectra were assigned for 15 new compounds, including E-Z isomers (all-E, 13Z, 9Z and 9Z,13Z) of retinoids containing an ethyl ester and car-boxylic acid polar end groups, and also the (all-E)-isomer of the retinoids with an alcohol and aldehyde polar end-groups and five C15 intermediates. The assignments were based on long-range 1H—13C heteronuclear 2D experiments.
