The synthesis of new series of 1β‐methylcarbapenems having a 2, 2‐disubstituted‐1, 3‐diazabicyclo[3.3.0]octan‐ and ‐[4.3.0]nonan‐4‐one moiety is described.Their in vitro antibacterialactivities against both Gram‐positive and Gram‐negative bacteria were tested and the effect of the substituent of the bicyclic ring was investigated. A particular compound (16 f) bearing a hydroxymethyl group showed the
