New structure-activityrelationships of a series of methylene or sidechain modified retinoids on NB4 acute promyelocytic leukemia cells are investigated. The differentiation- and apoptosis-inducing potential of these compounds is analyzed on the basis of their selective retinoic acid receptor binding profile.
New Synthetic Analogs of Retinoids: Synthesis of Aromatic Analogs of 9-Methylidene- and 13-Demethyl-9-methylidene-retinol, -retinal, and Ethyl 13-Demethyl-9-methylideneretinoate
Aromaticanalogs of 9-methylidene and 13-demethyl-9-methylideneretinol, -retinal, and ethyl 13-demethyl-9-methylideneretinoate were synthesized via a new β-methylidene-aldehyde synthon.

After halogen-metal exchange reaction followed by condensation with carbonylcompounds, ene diiodo acetal 1 allow the stereoselective synthesis of ene hydroxy acetals 2 with Z configuration, in a two step procedure. Moreover, after dehydration, the intermediate diene acetals 3–4, via an appropriated hydrolysis procedure, lead to pure non conjugated dienals 5.
