(Chemical Equation Presented) A method for selective mono-N-alkylation of amino alcohols is introduced. This method relies on formation of a stable chelate with 9-BBN, which serves in the dual roles of protecting and activating the amine group. Three prototypical amino alcohols featuring various three-carbon bridging units led selectively to the monoalkylated derivatives in very high yields. The straightforward synthesis of the N-CD3 derivatives demonstrates the effectiveness of this approach.
