Monunorillonite clays catalyze the rearrangement of substituted ally1 phenyl ethers to provide onho-ally1 phenols, chromans and coumaran s under mild conditions. The [3,33 sigmatropic shift (Claisen rearrangement) of ally1 aryl ethers provides convenient access to ortho-ally1 phenols, precursors to
The Claisen rearrangement of ally1 vinyl ethers is catalyzed by PdCQ(CH3CN)Z. provided that alkyl substituents protect the vinyl ether double bond from coordination by the metal catalyst. [3,3]Sigmatropic rearrangements are very useful for the formation of C-C, C-O, C-N and C-S bonds. Besides the cl
