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.
介绍了从光学活性 δ± 氨基酸合成 1-(2-吡啶基)烷基胺和 N-甲基或 N,N-二甲基-1-(2-吡啶基)烷基胺的一般方法。所介绍的程序基于合适的腈与乙炔的催化共环三聚反应,可以在不损失光学纯度的情况下进行。
