Alpha-hydroxyamides are synthesized from the cooresponding alpha-hydroxyacids by generation of the bis-trimethylsilyl derivative and treating it with oxalyl chloride. Following addition of the appropriate amine, the TMS ether is hydrolyzed in the workup to provide the desired alpha-hydroxyamide. As summarized in Table 1, this reaction has proven to be general and compatible with chiral alpha-hydroxyacids affording the desired alpha-hydroxyamides in excellent yield (77-99%).
