【Abstract】 The reductive amination of aldehydes and ketones with amines in the presence of sodium malonyloxyborohydride 1 prepared in situ from malonic acid and sodium borohydride in anhydrous THF is described. The reaction conditions and the steric hindrance effect for the reductive amination are also discussed. It was found that self-reduction of 1 did not occur under the experimental conditions.更多还原
