✦ Synopsis
A Note on Methods for the Transformation of 1,2‐Dicarboxylic Acids into α, β‐Unsaturated Monocarboxylic Acids.
A model study using the Diels‐Alder adduct of maleic anhydride and butadiene (see scheme 3) exemplifies the conversion of the succinic acid type of structure into α, β‐unsaturated carboxylic acids via two complementary fragmentations of 3,6‐dioxo‐perhydro‐1,2‐oxazine derivatives.
