摘要:Posaconazole, a clinically useful antifungal agent, has several known oxidative degradation products involving the piperazine ring near the center of the molecule. A novel degradant was recently isolated and characterized spectroscopically as a novel ring-contraction product incorporating a dihydroimidazolium moiety in lieu of the normally present piperazine ring.
