摘要

(1R, 11R, 5S, 6S)-2-[(2-N, N-dimethylamino)-2-iminoethyl)-thiol-6-(1-hydroxyethy1)-1- methylcarbapenem (1) possesses improved chemical stability at high concentrations and decreased susceptibility to renal dipeptidase-I while it retains an excellent antibacterial pr~ file.~ Although the synthesis of 1 via the key intermediates 2 and 3a, b has been reported recently: the methodology employed required epimerization, chromatographic separation, ...
