Synthesis of functional furan derivatives by oxidation of furans and formylfurans with hydrogen peroxide

Abstract

The review analyzes the effects of the reaction conditions on the direction of the reactions between furans/formylfurans and hydrogen peroxide. The revealed dependences serve for the synthesis of the desired products and for development of new methods to access α-hydroxy hydroperoxides of furan aldehydes, 2-furanoic acid and its esters and amides, a series of furoic acids bearing the substituent at the furan ring, 2(5H)-furanone and its homologs and functional derivatives, as well as 2,5-dialkoxydihydrofurans. The developed procedures are more advantageous than the conventional methods.
