Usage of α-picoline borane for the reductive amination of carbohydrates

The reaction of reductive amination, widely used for carbohydrates, was reviewed in our lab, especially in the context of the analytical determination of carbohydrate enantiomers. The best conditions for the technique have been evaluated, showing that under optimal working conditions it is possible...
