2, 3-cyclopentenopyridine, a pyridine derivative, is an important intermediate for the synthesis of cefpiro, and is also widely used in the preparation of plant protective agents, synthetic resins, plastic products, etc. As the fourth generation of new cephalosporins, cefpirome has the characteristics of broad spectrum, high efficiency, low toxicity and enzyme resistance, etc. It is the strongest antibacterial activity against Gram-positive bacteria among known cephalosporin Chemicalbook. It was first marketed in Sweden under the trade name CEFROM in 1992. Although cefpirome has been marketed and used in developed countries for 20 years, it has failed to form a scale due to the limitations of domestic economic and technological conditions and is still in its infancy.
