1,3-oxazolidines derived fromtris(hydroxymethyl)aminomethane (TRIS) and pyridine-based aldehydes. Divergent results were obtained with other formylpyridines, such aspyridoxal, in which intramolecular hydrogen-bonding largely stabilizes the iminic structure. The oxazolidines may undergo ring-opening under acetylating conditions to afford imines through different mechanistic pathways, which have also
