We herein report a simple and convenient one-pot synthesis of highly substituted 2-imidazolines in a regiocontrolled and stereospecific matter through the ringexpansionreaction of an imidoyl chloride with an aziridine, analogous to the Heine reaction.

The chiral aziridino alcohols 1 – 3 have been prepared either from amino acids (1a from serine; 1b – 1i and 3 from threonine; 2a – 2e from allo-threonine) or via asymmetric synthesis (1j, 1k, 1l and 2f from methyl cinnamate). These easily available ligands act as catalysts for the enantioselective addition of diethylzinc to benzaldehyde, with up to 90% stereoselectivity. The absolute configuration

An efficient approach towards peptide synthesis that allows easy access to variety of small peptides via one-pot aziridine-mediated ligation/desulfurization strategy has been described. The protocol afforded a library of phenylalanine- and tryptophan-containing α-peptides in good yields by regioselective ring-opening of aziridine-3-aryl-2-carboxylates with peptide thioacids, followed by desulfurization
