One-Pot Aminoalkylation of Aldehydes: Diastereoselective Synthesis of Vicinal Diamines with Azaarylmethylamines.

A one-pot synthesis of vicinal diamines with azaarylmethylamines and aldehydes is reported. A diverse array of vicinal diamines could be achieved in up to 92% yield with good to excellent diastereoselectivities (up to 20:1). The tandem reaction takes place under mild conditions and provides an alternative strategy for the synthesis of vicinal diamines.
