3-Vinyl oxindole-chromone synthon as a skeletal reconstruction reactant for the synthesis of 2-hydroxy benzoyl pyridones

Abstract

The first example of 3-vinyl oxindole-chromones in the ring opening and recyclization reaction.

Lewis Acid-Catalyzed Benzannulation of Vinyloxiranes with 3-Formylchromones or 1,4-Quinones for Diversely Functionalized 2-Hydroxybenzophenones, 1,4-Naphthoquinones, and Anthraquinones

“…2-Hydroxybenzophenones are significant and valuable compounds that can be widely found in bioactive natural products and pharmaceuticals, , and they are known to exhibit an extensive array of physiological and pharmacological effects . As a result, these compounds are frequently employed as building blocks in the synthesis of biologically interesting molecules and functional materials. , Some examples of bioactive natural products and functional molecules containing the 2-hydroxybenzophenone skeleton are shown in Figure A .…”
