YieldReaction ConditionsOperation in experiment
39% With piperidine; In acetonitrile; at 50℃; for 18h; General procedure: Aldehyde (1 equiv.) and acceptor compound (1 equiv.) were dissolved in acetonitrile (100 mL for 14 mmol). Piperidine (0.01 equiv.)was added and the solution was stirred at the temperature indicated forthe time indicated in each protocol. The solution was then concentratedunder vacuum and the product purified by column chromatography onsilica gel.
