Abstract:

An efficient procedure for the synthesis of β-keto esters from the reaction of aldehydes and ethyl diazoacetate catalyzed by iodine at room temperature under solvent-free conditions has been described. The catalytic procedure has the advantages of easily available catalyst, mild reaction conditions, high yields, and easy work-up.

Key words: Iodine; β-Keto ester; Aldehyde; Ethyl diazoacetate
