The highly enantioselective copper-catalyzed propargylic amination of propargylic esters with amine hydrochloride salts has been realized for the first time using copper salts with chiral N,N,P-ligands. This method features a broad substrate scope and wide functional group tolerance, generating propargylic amines in good to excellent yields with high enantioselectivities (up to 99% ee). The utility

,2′-di-carboxamide (15a); similar treatment of the amide (8b) affords the corresponding azoxybenzene derivative (16b) and benzaldehyde 2-carboxyphenylhydrazone (20). Mechanisms for the base-catalysedtransformations of the amides (6a and b) and (8a and b) are discussed.

The hydrohalides of 2-sec-aminoalkanenitriles on treatment with oxalyl halides in o-dichlorobenzene at 80-100° give 3, 5-dihalo-2(1H)-pyrazinones, of which the 3-halo substituent is easily replaced by nucleophiles. A reaction mechanism for the pyrazinone synthesis is proposed.

A process for preparing specific 1-substituted 5-hydroxy-imidazoline-2,4-diones by reacting glyoxylic acid with N-substituted ureas is provided, where this process is carried out in a 10-80% strength aqueous solution and in the presence of an acid catalyst. The 1-substituted 5-hydroxy-imidazoline-2,4-diones can subsequently be converted in a further reaction step to give 1-substituted 5-alkoxy-imidazoline-2,4-diones.
