  Copper-catalyzed desymmetrization of oxabenzonorbornadienes with aluminum reagents

  摘要：

  The desymmetrization of oxabenzonorbornadienes with aluminum reagents and SimplePhos as chiral ligand is described. The corresponding homoallylic alcohols are obtained in high yield, diastereoselectivity, and enantiomeric excess. Furthermore the first anti enantioselective desymmetrization with aromatic nucleophiles is reported. (C) 2009 Elsevier Ltd. All rights reserved.

  A new platinum-catalyzed anti-stereocontrolled ring-opening of oxabicyclic alkenes with various Grignard reagents was reported, which afforded the corresponding anti-2-substituted-1,2-dihydronaphthalen-1-ol products with moderate to good yields in the presence of a catalytic amount of Pt(PPh3)4 (2.5 mol%) under mild conditions. The effects of catalyst loading, solvent and temperature on the yield were

  A highly enantioselective method for the copper-catalyzed desymmetrization of oxabenzonorbornadienes with aluminum reagents and SimplePhos as chiral ligand has been developed. The same reaction with Grignard reagents is also reported. A wide range of alkyl chains have been used with moderate to high enantio­selectivity and high trans selectivity. The transfer of a methyl group is also reported with
