With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.95-15-8,Thianaphthene,as a common compound, the synthetic route is as follows.
95-15-8, General procedure: A flame-dried Schlenk test tube with a magnetic stirring bar was charged with Pd(dppf)Cl2 (0.0125 mmol, 2.5 mol%), Cu(OAc)2*H2O (0.1 mmol, 0.2 equiv.), N-heteroarene (1,0.5 mmol), pyridine (0.5 mmol, 1.0 equiv.) and 1,4-dioxane (1.0 mL). After the reaction mixture was stirred for 10 min at room temperature, thiophene, furan or indole (2, 1.5mmol, 3.0 equiv.) was added. The resulting mixture was heated at 140 C for 30 h under 1 atm of oxygen, and then cooled to ambient temperature. The mixture was diluted with 30 mL of CH2Cl2, filtered through a celite pad, and then washed with 10-20 mL of CH2Cl2. The combined organic extracts were concentrated and the resulting residue was purified by column chromatography on silica gel to provide the desired product.
The synthetic route of 95-15-8 has been constantly updated, and we look forward to future research findings.
