An atom-economical protocol for direct conversion of Baylis–Hillman alcohols to β-chloro aldehydes in water

This paper describes an atom-economical strategy for the direct conversion of Baylis–Hillman alcohols to β-chloro aldehydes under metal free conditions with excellent functional group tolerance. The use of stable-nontoxic Oxone as a terminal oxidant along with an inexpensive salt (sodium chloride) as a halogen source and water as the reaction medium makes this chemical synthetic process more viable and environmentally benign contributing towards green chemistry.
