Abstract
AbstractA direct oxidative esterification of α‐amino carbonyl compounds by two kinds of hydroperoxides, for the synthesis of α‐keto esters has been developed. The reaction shows broad substrates scope and good functional group tolerance, even for the synthesis of bulkyl esters, and is free of metal catalysts and external additives. Notably, the inhibitor of protein tyrosine phosphatases (PTPases) could be successfully synthesized with our protocol.
