Abstract:
A hydride transfer strategy for the synthesis of N-methylated primary, secondary amines, and N-methylated heterocyclic amines is reported. This protocol effectively converts diverse carbamates into N-methylated amines using bench-stable amidophosphine borane as a reducing agent. The reaction demonstrates a broad substrate scope and functional group tolerance under mild conditions. Additionally, the application of this protocol for the synthesis of pharmaceutically active butenafine analogues is shown.

Nitriles to Amines: LiAlH4 Reduction
As shown below, the mechanism involves three steps. Firstly, the hydride ion acting as a nucleophile attacks the nitrile carbon to form an anion. In the second step, a second equivalent of the hydride ion attacks the anion to...
Preparation of 1° Amines: Azide Synthesis
Azide ions act as good nucleophiles and react with unhindered alkyl halides to form alkyl azides. Alkyl azides do not participate in further nucleophilic substitution reactions, thereby eliminating the chances of polyalkylated products. Alkyl azides are reduced by hydride-based reducing agents, like lithium aluminum...
