  Synthesis and structure-activity relationships of novel THF 1β-methylcarbapenems

  摘要：

  A series of twelve highly active aminomethyl-THF 1 beta-methylcarbapenems 3a-1 were synthesized. Of these, carbapenems 3a-f demonstrated a spectrum of antimicrobial activity comparable to those of imipenem and meropenem with the exception of only moderate anti-pseudomonal activity. Most importantly, they demonstrated moderate intrinsic oral activity against an E. coli infection in mice. (C) 1997 Elsevier Science Ltd.

  日期：——

  Convergent syntheses of oral THF 1beta-methylcarbapenems 4 (OCA-983) and 5 starting from M2-phosphate 1 were developed. Reaction of the M2-phosphate 1 with THF thiols containing a requisite prodrug side chain, 9 and 10, gave the desired oral THF 1beta-methylcarbapenems 4 and 5, respectively, in 46% and 42% overall yields.

  A reproducible synthesis of 2,5-anhydro-1-amino-1,4-dideoxy-3-thio-D-threo-pentitol hydrochloride (2b) via the Staudinger reaction with triethyl phosphite was developed. An unexpected ethyl migration from an oxygen to the nitrogen of iminophosphorane 7 was observed.
