Description	The reaction of aldehydes (pentanal, benzaldehyde, 4-methoxybenzaldehyde, 4-nitrobenzaldehyde, salicylaldehyde, pyridin-2-carbaldehyde) with 1-aminocyclopentancarboxamide or (S)-2-amino-2,3-dimethylbutanamide has been used to prepare substituted imidazolidin-4-ones 1a-g in the yields of 53-83%.Subsequent oxidations with various reagents gave the corresponding 4,5-dihydro-1H-imidazol-5-ones 2a-g: Pd/C (72-93%), DDQ (25-80%), and MnO2 (30-77%). Structure of the prepared compounds 1a-g and 2a-g was verified by 1H NMR and 13C NMR spectroscopy, EI-MS and elemental analysis. X-ray diffraction was performed in the case of compounds 1e and 2e.
