YieldReaction ConditionsOperation in experiment
92% With copper(I) bromide; In toluene; at 100℃; for 4h;Inert atmosphere; Sealed tube; General procedure: To a vial equipped with a magnetic stir bar were added amine (1.5mmol, 14a-e), aldehyde (1.0mmol, 15), acetylene (3.0mmol, 16a-j), copper bromide (0.36mmol, 25mol%) and toluene (1.0mL). The reaction mixture was degassed and backfilled with argon. Then, reaction vessel was sealed and heated conventionally at 100C for 4h. The resulting reaction mixture was cooled to ambient temperature, diluted with dichloromethane (2mL) and purified by column chromatography with 10-15% EtOAc in heptane to afford the desired product ( 17a-x).
