Abstract

A smooth, organocatalytic one-pot oxidative cleavage of terminal 1,2-diols to one-carbon-unit-shorter carboxylic acids is catalyzed by 1-Me-AZADO in the presence of a catalytica amount of NaOCl and NaClO₂ under mild conditions. A broad range of substrates including carbohydrates and N-protected amino diols were converted without epimerization.
