Extended knowledge of tert-Butyl 2-oxo-5,6-dihydropyridine-1(2H)-carboxylate

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,128372-89-4, its application will become more common.

Electric Literature of 128372-89-4 ,Some common heterocyclic compound, 128372-89-4, molecular formula is C10H15NO3, 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: A dried Schlenk flask was charged with arylboronic acid (3, 0.4 mmol), [Rh(L1)(OH)]2 (L1=(S,S)-Ph-thpe, 3.8 mg, 0.005 mmol), KHF2 (3.2 mg, 0.04 mmol), and 1 mL of anhydrous toluene under argon. The resulting mixture was stirred at room temperature for 30 min. 1-N-Boc-2-oxo-5,6-dihydropyridine (2c, 39.4 mg, 0.2 mmol) in toluene (1 mL) was added. Seven minutes later, 0.1 mL of isopropanol was added. After being stirred at room temperature for 2 h, the reaction was quenched with saturated aq NH4Cl, extracted with ethyl acetate (20 mL×3), and the combined organic phases were washed with brine, dried with anhydrous Na2SO4, filtered, and concentrated. The residue was purified by silica gel (300-400 mesh) column chromatography to afford 4.

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,128372-89-4, its application will become more common.
