A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 14347-78-5, Name is (R)-(2,2-Dimethyl-1,3-dioxolan-4-yl)methanol, molecular formula is C6H12O3. In an article, author is Sayahi, Mohammad Hosein,once mentioned of 14347-78-5, COA of Formula: C6H12O3.
Cu(OAc)(2) Catalyzed Synthesis of Novel Chromeno [4,3-b]Pyrano[3,4-e]Pyridine-6,8-Dione Derivatives via a One-Pot Multicomponent Reaction in Water under Mild Reaction Conditions
An efficient method is introduced based on the copper(II) acetate catalyzed one-pot multicomponent synthesis of novel chromeno[4,3-b]pyrano[3,4-e]pyridine-6,8-dione derivatives under mild reaction conditions in water as a green solvent. The synthesis involves the multicomponent reaction of 4-aminocoumarin, 6-methyl-2H-pyran-2,4(3H)-dione, and aldehydes in the presence of 10 mol% of copper(II) acetate as catalyst under mild reaction conditions. Eight different derivatives are synthesized using various benzaldehydes with different functional groups. All the produced chromeno[4,3-b]pyrano[3,4-e]pyridine-6,8-diones were synthesized successfully in very good isolated yields. A possible mechanism was proposed and presented. In general, the method is simple and is based on commercially available reagents and catalyst.
