Cycloaddition reactions of o-quinone methides with polarized olefins Russ. Chem. Rev. (IF 7.7) Pub Date : 2021-03-30 Vitaly A. Osyanin, Anton V. Lukashenko, Dmitry V. Osipov
The review summarizes and systematizes the [4+2]-cycloaddition reactions of o-quinone methides with electron-rich and electron-deficient olefins. The electron-rich substrates include vinyl ethers, vinyl sulfides, enamines, enamides, enols, furans, benzofurans and indoles, while the electron-deficient substrates are esters of unsaturated carboxylic acids, vinyl azides and quinones. Reactions with push-pull
