The first Cu(II)-catalyzed highly enantioselective intramolecular cyclization of N-alkenylureas was developed for the concise assembly of chiral vicinal diamino bicyclic heterocycles. Facile removal of carbonyl group of the carbamido moiety allowed for ready access to enantioenriched cyclic vicinal diamines.

In this work, synthesis, characterization and antimicrobial activity of series of imidazolines-oxazolines scaffolds 5a-f and 10a-d have been investigated. All the imidazolines-oxazolines derivatives were prepared from acid derivatives 1 and 6a-c, and enan

A series of novel chiral ligands L1-L4 with an imidazoline-oxazoline framework have been developed as new type of non-symmetric N,N-bidentate ligands. All the chiral ligands were prepared from 2,2-diethylmalonic acid and enantiomerically pure (S)-2-amino-

Upon irradiation of trithiobarbiturate (1), ring contraction reaction occurred to give thiohydantoin (2 or 3) and imidazolinothiophene (4) derivatives. Further, on treating with iodine, the thiohydantoins (2 and 3) undergo ring closure, giving imidazolino
