    The suzuki reaction in stereocontrolled polyene synthesis: Retinol (vitamin A), its 9- and/or 13-demethyl analogs, and related 9-demethyl-dihydroretinoids
    摘要:
    A new synthesis of retinol (vitamin A) and 9- and/or 13-demethylretinols, with essentially complete control of regio- and stereochemistry, is described which is based on the thallium-accelerated, palladium-catalyzed cross-coupling reactions of (E)-1-alkenylboronic acids and (E)-1-alkenyl iodides (Suzuki reaction). The procedure has also been extended to the stereocontrolled synthesis of a series of 9-demethyl-dihydroretinoids of potential biological interest.

    摘要:
    A stereospecific synthesis of 9-demethylretinoids with either trans or 11-cis geometries, based on the thallium-accelerated palladium-catalyzed cross-coupling reactions of an (E)-1-alkenylboronic acid and (E) or (Z)-alkenyl iodides, is described.

    13-desmethyl-vitamin A are described from the corresponding desmethyl homologues of vitamin A acid methyl esters. The latter were prepared by condensation of trans-β-ionylidene acetaldehyde and trans-5-(2′,6′,6′-trimethylcyclohexene-1′-yl-1′)-pentadiene 2,4-al-1 respectively, with the phosphonates of the appropriate crotonic acid esters. Biological investigations on growth promoting properties have shown that all-trans-13-
