Recent Advances in the Chemistry of Morita–Baylis–Hillman (MBH) Carbonates: A Review

Morita-Baylis-Hillman carbonates are a versatile and emerging class of organic precursors, utilized in various organic transformations as a main reagent, yielding intricate functionalized moieties. These carbonates facilitate the synthesis of various bioactive entities, natural products, and other valuable compounds. MBH carbonates combined with other substrates such as phenolates, oxindole-chromones, enamino maleimides, isoquinolines, sulfones, cyclic ketimines/imines, and perfluoroalkyls, and so forth via substitution and annulation reactions provide valuable organic compounds. This review highlights the recent synthetic applications of these organic carbonates in the synthesis and functionalization of oxindoles, pyrazoles, quinolines, and organofluorides, and so forth.
