Environmentally benign synthesis of 1,8-dioxooctahydroxanthene derivatives using 10-molybdo-2-vanadophosphoric acid as an efficient and reusable catalyst under solvent-free condition
A green and efficient protocol for the synthesis of 3,3,6,6-tetramethyl-9-aryl-1,8-dioxooctahydroxanthene derivatives via cyclocondensation of 5,5-dimethyl-1,3-cyclohexanedione and aromatic aldehydes in the presence of catalytic amount of 10-molybdo-2-vanadophosphoric acid under solvent-free conditions has been described. The 10-molybdo-2-vanadophosphoric acid was prepared and characterized by ...

متن کاملRecyclable Boron Sulfonic Acid as an Environmentally Benign Catalyst for the One-Pot Synthesis of Coumarin Derivatives under Solvent-Free Condition
A mild and green method has been developed for the preparation of coumarins derivatives through the one-pot reactions. In our study,various phenols and ethyl acetoacetate compound in which we used silica-supported boron sulfonic acid [SiO2/B(SO4H)3] as a new, highly efficient and tri-functional inorganic Brønsted acid catalyst were processed under solvent-free condition and thermal. The catalys...
متن کاملSynthesis of (±)-(10-2H, 11-2H2,12-2H3)Jasmonic Acid
Jasmonic acid (JA) and methyl jasm onate (JA-Me, 1) are naturally occurring substances in plants. They are representatives of a group of plant growth regulators [1], The exact quantifica tion of JA in plant materials is of great interest for further studies on transport, metabolism and en dogenous importance of JA. Using the GC/M SSIM method deuterium-labelled JA should be a good internal sta...
متن کاملReusable Silica supported Perchloric acid and potassium bisulphate as green catalysts for thiocyanation of aromatic compounds under solvent free conditions
Reusable silica supported perchloric acid and potassium bisulphate have been prepared and explored as green catalysts for thiocyanation of aromatic compounds under conventional and solvent free microwave assisted conditions. The microwave assisted protocol exhibited remarkable rate accelerations and offered selective thiocyanation of aromatic and hetero aromatic compounds in good yields. Reacti...
