N-(α-Aminoalkyl)benzotriazoles, prepared from a variety of aldehydes and secondary amines, react with diverse ester enolates, sulfones, a sulfoxide, alkylated pyridines, and nitriles to provide novel access to β-amino carboxylic esters (55-80% yield), β-aminoalkyl sulfones (42-88% yield), β-aminoalkyl sulfoxides (20-32% yield), α- and γ-(β- aminoalkyl)pyridines (69-90% yield), and β-aminoalkyl cyanides (10-97% yield), respectively.

The asymmetric synthesis of β2,2-amino acids remains a formidable challenge in organic synthesis. Here a novel organocatalytic enantioselective aminomethylation of ketenes with stable and readily available N,O-acetals is reported, providing β2,2-amino esters bearing an all-carbon quaternary stereogenic center in high enantiomeric ratios with a catalytic amount of chiral phosphoric acid. Typically, this transformation probably proceeds through an asymmetric counter-anion-directed catalysis. As a result, a concise, practical, and atom-economic protocol toward rapidly access to β2,2-amino acids has been developed.
Classical benzotriazole-mediated α-aminoalkylations of alkynes: Synthesis and characterization of alk-2-yn-1-amines as amphiphilic materials

Reactions of readily available and stable benzotriazolemethanamines 1a-1, obtained from aldehydes and secondary amines (Scheme 2), gave the expected alk-2-yn-1-amines 3a-t (Scheme 3). The amphiphilic character of the synthesized products was responsible f
