SYNTHETIC INVESTIGATIONS IN THE CHEMISTRY OF POLYENE COMPOUNDS. XLV. SYNTHESIS OF ANALOGS OF VITAMIN A STRUCTURALLY SIMILAR TO ITS METABOLITES

The synthesis of the C2O retinoids 15-methoxy- and 15-acetoxy-9,13-dimethyl-7-(1,5-dimethyl-1-ethoxycarbonyl-4-oxo-5-cyclohexen-6-yl)-7,9,11,13-nonatetraenes was realized under the conditions for carbonyl olefination by the Wittig method from 2-oxo-4-(2,6
