  Stereospecific synthesis of 9-demethylretinoids via palladium-catalyzed vinylboronic acid-vinyl iodide cross coupling

  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.

  A novel approach to the synthesis of retinoids and arotinoids (including heterocyclic analogs) is described which is based on the thallium-accelerated palladium-catalyzed cross-coupling of boronic acids with a variety of electrophiles (the Suzuki reaction).

  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.
