Solvent-free synthesis of 14-Aryl-14H-dibenzo[a,j]xanthenes catalyzed by recyclable and reusable iron(III) triflate

A solvent-free and efficient synthesis of 14-aryl-14H-dibenzo[a,j]xanthenes through the one-pot condensation of β-naphthol and aldehydes catalyzed by recyclable and reusable Iron(III) triflate was reported. Notably, the presented method features short rea

Enantioselective Pd0-Catalyzed C(sp2)–H Arylation for the Synthesis of Chiral Warped Molecules

C?H activation-based ring-forming methods are a powerful approach for the construction of complex molecular architectures, especially those containing a congested stereocenter. Therefore, this strategy seems perfectly suited to address the synthesis of ch

High acidity cellulose sulfuric acid from sulfur trioxide: A highly efficient catalyst for the one step synthesis of xanthene and dihydroquinazolinone derivatives

A cellulose sulfonate catalyst (HS-cellulose sulfonate) with high stability, excellent catalytic activity and high acidity value (about 1.55 mmol g-1) was successfully prepared by SO3 gas phase sulfonation. The basic morphology and nanostructure of the catalyst were determined by HRTEM, XRD, IR, TG, etc. In addition, the catalyst was applied to the catalytic reaction of a dihydroquinazolinone derivative and a xanthene compound, and very valuable results were obtained. The development and preparation of cellulose sulfonate catalysts provide a good approach for the development and application of cellulose, and also an important application of green organic catalytic synthesis methodology.
