Overman rearrangement

The Overman rearrangement is a chemical reaction that can be described as a Claisen rearrangement of allylic alcohols to give allylic trichloroacetamides.[1][2][3][4] The Overman rearrangement was discovered in 1974 by Larry Overman.[5]

The [3,3]-sigmatropic rearrangement is diastereoselective and can be catalyzed by heat, Hg(II), or Pd(II). The resulting allylamine structures can be transformed into many chemically and biologically important natural and un-natural amino acids (like (1-adamantyl)glycine).[6]
