SYNTHETIC INVESTIGATIONS IN THE CHEMISTRY OF POLYENE COMPOUNDS. XLVI. THE TOTAL SYNTHESIS OF ETHYL-rac-(2E,4E,6E)-5-METHYL-7-(2,6-DIMETHYL-6-ETHOXYCARBONYL-3-OXO-1-CYCLOHEXENYL)-2,4,6-HEPTATRIANOATE

The synthesis was realized of the previously unknown C17 retinoid ethyl-rac-(2E,4E,6E)-5-methyl-7-(2,6-dimethyl-6-ethoxycarbonyl-3-oxo-1-cyclohexenyl)-2,4,6-heptatrienoate by the C10 + C7 C17 scheme and the C15 retinoid ethyl-rac-(2E,4E)-3-methyl-5-(2,6-dimethyl-6-ethoxycarbonyl-3-oxo-1-cyclohexenyl)-2,4-pentadionoate by the C10 + C5 C15 scheme.

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
