borane-mediated reduction of imines and reductive N-alkylation with carbonylcompounds is described. This protocol’s reducing agent is only borane in the reduction of imines, and additional reductant is not necessary in reductive N-alkylation step. When using more than two equivalents of aldehydes, reductive N-alkylation proceeded in good yield. reductive N-alkylation -boranereduction- imines - tertiary
