Résumé A series of trans- and cis-3,4-disubstituted 5-oxomorpholine-2-carboxylic acids 5 were prepared by a cyclocondensation between diglycolic anhydride 3 and arylideneamines 4. Transformations of the carboxylic group leading to a peptide bond in the side chain to the morpholinone ring were effected. The relative configurations and the preferred conformations of the substituents at the morpholinone ring in some of the newly prepared derivatives were determined by means of 1H NMR and X-ray analysis.

cationic poly-ionic liquid (PIL) with a cobalt(II) chloride anion. The resulting material has a core-shell structure that displays excellent activity and selectivity in the self-dehydrogenation and hetero-dehydrogenation of primaryamines to their corresponding imines. Furthermore, the catalyst exhibits excellent activity in the synthesis of secondary iminesfrom substrates with various reducible functional

homoleptic complexes of Co(II) [C-1], Ni(II) [C-2], Cu(II) [C-3], and Zn(II) [C-4] derived from N-(4-methoxybenzyl) N-(phenylethyl) dithiocarbamate ligand (KL) with general formula ML2 were synthesized with good yield and characterized by elemental analysis and different spectroscopic techniques like FTIR, 1H and 13C NMR, HRMS, UV-vis and fluorescence spectroscopy. The crystal structure of the complex C-4
