Chiral Ligands Containing Heteroatoms; 9.¹General Procedures for the Synthesis of Optically Active 1-(2-Pyridyl)alkylamines from α-Amino Acids

Abstract

General syntheses of 1-(2-pyridyl)alkylamines and N-methyl or N,N-dimethyl-1-(2-pyridyl)alkylamines from optically active α-amino acids are described. The presented procedures are based on catalyzed co-cyclotrimerization of the suitable nitriles with acetylene which can be conducted without loss of optical purity.
