Li, Yankun published the artcileSynthesis of Benzofuran Derivatives via a Gold-Catalyzed Claisen Rearrangement Cascade, Computed Properties of 312-40-3, the publication is Organic Letters (2022), 24(31), 5829-5834, database is CAplus and MEDLINE.
A novel method toward a facile synthesis of diverse benzofuran derivatives I [R = Me, Et, Ph, etc.; R1 = Me, Et] from easily obtained quinols and alkynyl esters was reported. A gold-catalyzed intermol. alkoxylation/Claisen rearrangement/condensation cascade was involved. The introduction of difluorodiphenylsilane as a water-trapping reagent in the reaction led to a higher yield.
Organic Letters published new progress about 312-40-3. 312-40-3 belongs to catalysis-chemistry, auxiliary class Organic Silicones, name is Difluorodiphenylsilane, and the molecular formula is C12H10F2Si, Computed Properties of 312-40-3.
