Retinoids and Related Compounds. Part 9. Synthesis and Spectral Characteristics of Retinal Analogues involving the 11-cis-Locked-cyclopentatrienylidene Structure

The 11-cis-locked-cyclopentatrienylideneretinals (7a), (7b), (8a), (8b), and (9) have been obtained in a short-path synthesis from the β-ionyl sulphone (3).Their characteristic spectral properties (u.v. and 1H n.m.r.) are discussed.
