Note:
This reaction has important synthetic applications for the synthesis of frameworks of numerous natural products, such as β,γ-unsaturated @C00852@ from @P04613@ of α,β-unsaturated carboxylic acid derivatives, excluding the use of strong bases, as required for similar isomerizations performed in the @G02704@.
