SolventFree BallMilling Biginelli Reaction by
Reactions were performed under solventfree, metalfree, mechanochemical (ball milling) and ambient laboratory conditions. Br + catalyzed oxidation of benzyl alcohols led to the product benzaldehydes and byproduct H + which were further promoted as component and catalyst, respectively, for a cascade transformation to dihydropyrimidones within the same reaction pot.
