Retinoids. 6. Preparation of alkyl- and trimethylsilyl-substituted retinoids via conjugate addition of cuprates to acetylenic esters

Five retinoids bearing the ethyl, tert-butyl, and trimethylsilyl groups in the 9-position of retinal and the ethyl and tert-butyl groups in the 13-position have been synthesized. The key step of the syntheses involves the conjugate addition of lithium die

19,19,19- AND 20,20,20-TRIMETHYLRETINAL: SIDE CHAIN TERT-BUTYL SUBSTITUTED RETINALS

The 11-cis, 13-cis, 11,13-dicis, and 9,11,13-tricis isomers of 19,19,19-trimethylretinal (1) and the 13-cis and 11,13-dicis isomers of 20,20,20-trimethylretinal (2) were synthesized and characterized.The Dess-Martin reagents is an effective oxidant for the retinol to retinal conversion.
