Reference of 32024-15-0, These common heterocyclic compound, 32024-15-0, name is 3-Iodo-4,5-dimethoxybenzaldehyde, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
General procedure: K2CO3 (2.5 × 10-4 mol, 2.5 equiv), aryl iodide (1.0 × 10-4 mol, 1.0 equiv), and alkyne (1.5 × 10-4 mol, 1.5 equiv) were mixed in a 10-mL vial, followed by addition of a solution of the selected catalyst (1 × 10-8 mol) in EtOH (1 mL). The vial was placed in a preheated oil bath at 80 C and stirred for 1 h. After cooling to 20-25 C, the reaction mixture was evaporated to dryness under a stream of dinitrogen followed by addition of 1.0 equiv of 1,2-dimethoxyethane as NMR internal standard, and extraction of the reaction mixture with three 0.20-mL portions of CDCl3. All fractions were joined and analyzed by 1H NMR spectroscopy. The product peak assignments were based on the authentic samples or on published dat, whereas quantifications were performed upon integration of the selected peak of the product relatively to the peak of the standard.
Statistics shows that 3-Iodo-4,5-dimethoxybenzaldehyde is playing an increasingly important role. we look forward to future research findings about 32024-15-0.
