## Abstract The 5(4__H__)‐oxazolones 1a–e react with 5‐morpholinoisoxazoles 2a–b to afford the 4‐[(4‐isoxazolyl)methyl]‐5(4__H__)‐oxazolones 3a–g. Compounds 3 are hydrogenated with Pd/C in dioxane to yield the corresponding 1,4,5,6‐tetrahydro‐6‐oxo‐3‐pyridinecarbaldehydes 6a–d.
The title compound, [Fe(C~5~H~5~)(C~9~H~10~NO~2~)], was prepared from ferrocenecarboxylic acid and serine. In the crystal structure, molecules are arranged in chains with an intermolecular hydrogen bond between hydroxy groups and N atoms.
