Yield:39217-91-9 82%
Reaction Conditions:
with iodine;4,4,5,5-tetramethyl-[1,3,2]-dioxaboralane in dichloromethane at 20; for 24 h;
Steps:
5 The specific synthetic steps of 5-nitro-tetrahydroquinoline are as follows
Elemental iodine (0.05 mmol) and 5-nitro-quinoline (0.25 mmol) were added to the reaction flask to displace the air.Dichloromethane (1 mL) and pinacol borane (1 mmol) were added separately;After stirring at room temperature for 24 hours,The reaction mixture was diluted with methylene chloride (5 mL).Concentrated to a crude product,The crude product was separated by column chromatography (ethyl acetate: petroleum ether 1% to 10%).5-nitro-tetrahydroquinoline, yellow solid,The yield was 82%.
