A highly efficient and chemoselective dual functionalization of unprotected phenols with α- or β- hydroxyl acids was presented. A variety of valuable benzofuranones and dihydrocoumarins were delivered in moderate to high yields. D. functional theory (DFT) calculations and control experiments indicated that an untypical Friedel-Crafts alkylation and the subsequent lactonization were catalyzed by the Lewis acid form and the Bronsted acid form of borane, resp. Gram-scale experiments and late-stage functionalization of complex mols. were performed to highlight the utility of this reaction. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Quality Control of 4-Benzyloxyphenol).
4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Quality Control of 4-Benzyloxyphenol
