Cross-Coupling of Alkyl Redox-Active Esters with Benzophenone Imines: Tandem Photoredox and Copper Catalysis

Alkyl amines are an important class of organic compounds in medicinal and materials chemistry. Until now very have been very few methods for the synthesis of alkyl amines by metal-catalyzed cross-coupling of alkyl electrophiles with nitrogen nucleophiles. Described here is an approach to employ tandem photoredox and copper catalysis to enable the cross-coupling of alkyl N-hydroxyphthalimide esters, readily derived from alkyl carboxylic acids, with benzophenone-derived imines. Hydrolysis of the coupling products furnish alkylated primary amines. Primary, secondary, and tertiary alkyl groups can be transferred, and the coupling tolerates a diverse set of functional groups. The method allows rapid functionalization of natural products and drugs, and can be used to expedite syntheses of pharmaceuticals from readily available chemical feedstocks.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.33024-60-1,Tetrahydro-2H-pyran-4-amine hydrochloride,as a common compound, the synthetic route is as follows.

Example 79 (2E)-3-{1-[bis(4-fluorophenyl)methyl]-3-cyano-4,6-dimethyl-1H-pyrrolo[2,3-b]pyridin-2-yl}-N-(tetrahydro-2H-pyran-4-yl)prop-2-enamide To a solution of (2E)-3-{1-[bis(4-fluorophenyl)methyl]-3-cyano-4,6-dimethyl-1H-pyrrolo[2,3-b]pyridin-2-yl}prop-2-enoic acid (250 mg, 0.570 mmol) in THF (2.5 ml) were added DMF (0.025ml) and oxalylchloride (0.060 ml, 0.680 mmol), the mixture was stirred at room temperature for 1 hour and the solvent distilled off under reduced pressure. The residue was added under ice-cooling to a solution of tetrahydro-2H-pyran-4-ylamine hydrochloride (136 mg, 1.13 mmol), triethylamine (0.472 ml, 3.39 mmol) and THF (3 ml), and the mixture was stirred under ice-cooling for 2 hours and at room temperature for 12 hours. The reaction solution was poured into water and extracted with ethyl acetate. The extract was washed with water and dried over anhydrous magnesium sulfate, and the solvent was distilled off under reduced pressure. The residue was purified by silica gel column chromatography (hexane: ethyl acetate = 2: 1) to give the objective product as a solid material. The resultant material was recrystallized from hexane and ethyl acetate. Yield (amount) 200 mg, yield (rate) 66.7percent 1H-NMR (CDCl3) delta: 1.43-1.58 (2H, m), 1.87-1.92 (2H, m), 2.56 (3H, s), 2.75 (3H, s), 3.42-3.50 (2H, m), 3.94-4.05 (3H, m), 5.56 (1H, d, J = 7.8 Hz), 6.78 (1H, d, J = 15.3 Hz), 6.91-7.21 (9H, m), 7.43 (1H, d, J = 15.3 Hz), 7.92 (1H, s).
