    • The invention provides a novel compound of Formula II which is useful in the preparation of imipenem monohydrate of Formula I, wherein R1 is a p-nitrobenzyl or p-methoxybenzyl group; and R2 and R3 may be identical to or different from each other and are each independently a C1-6alkyl or aryl group, or a derivative thereof, and a process for preparing the compound of Formula II by coupling (5R,6S) p-nitrobenzyl-3-(diphenylphosphono)-6-[(1R)-1-hydroxyethyl]-1-azabicyclo[3.2.0]hept-2-ene-7-one-2-carboxylate with 2-aminoetahnethiol hydrocloride in the presence of a base, followed by a reaction with a ketone. Further, the invention provides a process for preparing the compound of Formula I by reacting a compound of Formula II with isopropylformimidate or benzylformimidate in the presence of a base, followed by hydrogenation, separation and crystallization.
    • 本发明提供了一种新的式II化合物,其可用于制备式I的亚胺培南一水合物,其中R 1为对硝基苄基或对甲氧基苄基; 并且R 2和R 3可以彼此相同或不同,并且各自独立地为C 1-6烷基或芳基或其衍生物,以及通过将(5R,6S)对硝基苄基 -3-(二苯基膦酰基)-6 - [(1R)-1-羟乙基] -1-氮杂双环[3.2.0]庚-2-烯-7-酮-2-羧酸叔丁酯与2-氨基乙脑二醇氢氯化物 碱,然后与酮反应。 此外,本发明提供了通过在碱的存在下使式II化合物与异丙基甲酰亚胺酯或苄基甲酰亚氨酸酯反应,然后氢化,分离和结晶来制备式I化合物的方法。
