Abstract

A simple and efficient method is reported for rapid chemoselective transformation of 1,1-diacetates to the parent aldehydes using 1,3-dibromo-5,5-dimethylhydantoin or N-bromosuccinimide in the presence of wet SiO2 (50%, w/w) as solid support under solvent-free conditions at room temperature. This procedure has valuable advantages, for example short reaction times, simple workup, high yields of products, absence of solvent, and use of commercially available and non-toxic reagents
