Abstract

Schiff bases of 3‐hydroxypyridin‐4‐carboxaldehyde and L‐α‐amino esters as well as those derived from the structurally related amines lacking the ester function have been synthesised. In two cases a tetrahydro‐1__H__‐imidazo[4,5‐c]pyridine was formed as a by‐product. ^1^H, ^13^C, ^15^N‐NMR spectral data and density functional theory (DFT) calculations established the structure of all compounds.

A series of esters derived from 3-methyl-2,4-diphenyl-3-azabicyclo[3.3.1]nonan-9a-ol (1) was synthesized and studied by 1 H and 13 C NMR spectroscopy, and the crystal structure of 3-methyl-2,4-diphenyl-9a-(3,5dimethylbenzoyloxy)-3-azabicyclo[3.3.1]nonane (2) was determined by x-ray diffraction. The
