Synthesis And Reactions Of Alpha-keto-beta-hydroxyphosphonates

Baris, Sehriban 01 February 2007 (has links) (PDF)
This thesis presents synthesis and different reactions of alpha-keto-beta-hydroxyphosphonates. Toward this aim, the hydroxyl functionality of alpha-hydroxycarboxylic acids were protected with alkyl or acyl groups and then formation of acid chloride followed by the reaction with trialkylphosphite furnished protected alpha-keto-beta-hydroxyphosponates. Nucleophilic addition reactions were applied to these compounds to obtain quaternary alcohols with phosphonate functionality. The addition reactions were tried with organocatalysts for the enantioselective formation of desired products.
