  名称：

  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.
