[3,3]-Sigmatropic rearrangements: a variety of methods and recent advances

The systematic review integrates and analyzes data on [3,3]-sigmatropic rearrangements published in the past decade. The main types of [3,3]-sigmatropic rearrangements are highlighted, optimal catalytic systems for various types of transformations and for various classes of compounds are considered. Examples are given for the use of such reactions in the synthesis of structurally complex, biologically active, natural and practically valuable compounds. For a number of processes, general mechanistic features of their behaviour, the geometry of transition states and the structures of inermediates are discussed.
