摘要：
Alum mediated solvent free, microwave enhanced, clean process for the production of alpha beta-unsaturated acids 3, 5 and 7 is described. Only 10 mole % of alum is enough in this protocol to achieve optimal yields and this protocol is fairly general and applicable to heterocyclic aldehydes and benzopyran 3-aldehydes.
