The resolution of N-t-Boc-piperazine carboxamide 5 proceeded smoothly in the presence of leucine aminopeptidase to produce acid (S)-1 and amide (R)-5 with good optical purity. Sequential alkylation and functional group manipulation of carboxamide (S)-5 provided the known nucleoside transport blocker (-)draflazine 2.

A series of 1-piperazinyl-N-phenylacetamide derivatives of 4,5-diphenyl-oxazoles, thiazoles, and imidazoles which are novel adenosine transport inhibitors have been found to provide effective antiischemic protection for CNS and cardiac tissue, particularly neurons. A method of treatment to protect against CNS ischemia, such as that resulting from trauma, stroke, or other ischemic conditions, comprises administration of these novel compounds to an individual in need of such treatment.
