The diastereoselective arylation of arabinofuranose derivatives using bromomagnesium phenolates: Synthesis of β-D- and α-L-arabinofuranosyl phenols

Add time:07/20/2019    Source:sciencedirect.com

The direct arylation of either antipodes of 2,3,5-tri-O-benzyl arabinofuranose (D-2 and L-2) at the anomeric sites by means of bromomaegnesium salts of activated phenols (1a-d) in 1,2-dichloroethane furnishes β-D- and α-L-arabinofuranosylphenols (D-3 and L-3) with very high margin of regio- and stereoselectivity.
