Studies in reductive amination. Part I. Aminoalkylpiperidines from 2-hydroxy-1,6-hexanedial
Abstract
High-temperature catalytic reductive amination of 2-hydroxy-1,6-hexanedial in ethanol gives low yields of mixtures of heterocyclic bases including 2-aminomethylpiperidine, 2-ethylaminomethylpiperidine, and related compounds. In aqueous medium 2-aminomethylpiperidine and probably 2-hydroxymethylpiperidine are produced.
