Piperazinedione prostaglandinanalogues (10) have been prepared from the previously described di-substituted glycine esters (8). The corresponding pyrazolidinediones (27) and triazolidinediones (30) were obtained by multi-step synthesis from ethyl carbazate (19)via the common intermediates (23). An oxadiazolidinedione (37) and a thiadiazolidinedione (40b) are also described. The piperazinedione (10c)
