This review covers the key advances in the study of Claisen rearrangement under microwave irradiation conditions. It surveys [3,3] sigmatropic rearrangements of vinyl allyl ethers, aryl allyl ethers, ortho-ester and aza Claisen rearrangements. Applications of the method for the synthesis of heterocyclic and natural compounds are surveyed.
