1593-08-4, 2-Formylquinoxaline is a quinoxaline compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
To a solution of commercially available quinoxaline-2-carbaldehyde (0.500 g, 3.16 mmol) in DCM (14.0 mL) were added 2-methylpropane-2-sulfinamide (0.383 g, 3.16 mmol) and Ti(OEt)4 (3.31 mL, 15.8 mmol). The reaction mixture was refluxed for 17 h, cooled to room temperature and quenched with water. The solids were filtered through a CELITE pad and washed with DCM. The organic phase was separated and washed with water, brine, dried over anhydrous Na2S04 and concentrated in vacuo. The residue was purified by flash chromatography (silica gel, hexanes:EtOAc, 100:0 to 50:50) to yield Int-16A (0.690 g, 84%) as a tan solid. NMR (500MHz, DMSO-c) delta 9.54 (s, 1H), 8.68 (s, 1H), 8.29 – 8.17 (m, 2H), 8.06 – 7.92 (m, 2H), 1.27 (s, 9H). HPLC retention time (Method 2): 2.132 mia; LCMS (ES): m/z 262.2 [M+H]+., 1593-08-4
The synthetic route of 1593-08-4 has been constantly updated, and we look forward to future research findings.
