Photoinduced reaction of conjugated compounds
(e.g., enones and carboxylic acid derivatives) leading to loss of
conjugation.
Note:
This reaction has important synthetic applications for the synthesis of
frameworks of numerous natural products, such as
β,γ-unsaturated
carboxylic acids from
photoexcitation of
α,β-unsaturated carboxylic acid derivatives, excluding the use of
strong bases, as required for similar isomerizations performed in the
ground state.
