have been prepared. Synthesis of the 15-aza derivative is based on a novel transformation of a ketone to an N-substituted ethylenamine using a formylmethylimino phosphate derivative. Several of the azaprostanoic acid derivatives were found to be potent inhibitors of platelet aggregation induced by arachidonic acid, whereas no effect was observed on ADP-induced primary aggregation, indicating blockade
