most efficient methods for amine synthesis. Herein we report a practical homogeneous DRA procedure utilizing iridium catalysis. Applying simple, readily available and inexpensive PPh3 and alike ligands along with iridium at a low loading, aldehydes and ketones reductively coupled with primary and secondary amines to efficiently form structurally and functionally diverse amine products, including a set

A practical stereospecific directamination of benzylic pinacol boronates was achieved by using 4-amino-4-methylmorpholinium iodide as a new amination reagent and cesium carbonate as the base. After amination, an in situ reductive N-alkylation with an aldehyde proceeded well to produce secondary amines.
