    • PURPOSE: Arylcarbonylazetidine-substituted carbapenem derivatives with anti-bacterial activity against resistant strains and a preparation method thereof are provided, which carbapenem derivatives have improved anti-bacterial activity against resistant strains such as methicillin resistant Staphylococcus aureus(MRSA) and ofloxacin resistant Staphylococcus aureus(QRSA). CONSTITUTION: The arylcarbonylazetidine-substituted carbapenem derivatives represented by formula (1) or pharmaceutically acceptable salts thereof are provided, wherein n is 0 or 1; Ar is aromatics or aromatics of which ring contains nitrogen which are optionally substituted with halogen, hydroxy or lower alkyloxy; and M is hydrogen or pair ion forming pharmaceutically acceptable salts. The method for preparing the arylcarbonylazetidine-substituted carbapenem derivatives of formula (1) comprises the steps of: (i) heating 3-(tert-butyldimethylsilyloxy) azetidin of formula (5) and arylcarbonylchloride of formula (6) in the presence of organic base in organic solvent to prepare acylated compound of formula (7); (ii) adding 4N hydrochloric acid into the acylated compound of formula (7) in methyl alcohol solvent and stirring the mixture at 0 to 5 deg. C for 1 to 3 hours to prepare tert-butylsilyl removed compound of formula (8); (iii) reacting the compound of formula (8) with triphenylphosphine and diethylazodicarboxylic acid or diisopropylazocarboxylic acid at -5 to 5 deg. C for 30 minutes to 2 hours, and adding thio acetic acid into the reacting compound and reacting them at room temperature for 1 to 3 hours to prepare a compound of formula (9); (vi) reacting the compound of formula (9) with base to prepare a compound of formula (3); reacting the compound of formula (3) with a compound of formula (2) to prepare carbapenem ester derivatives of formula (4); and removing carboxy protecting group and optional carboxyl protecting group from the compound of formula (4), wherein R1 is hydrogen, or hydroxy protecting group such as tert-butylmethylsilyl or triethylsilyl; and R2 is carboxyl protecting group such as p-nitrobenzyl, allyl or p-methoxybenzyl.
