A process for producing a 2-(unsubstituted or carbon-substituted)-1-carbapen-2-em-3-carboxylic acid derivative, which comprises reacting a 2-trifluoromethanesulfonyloxy-1-carbapen-2-em-3-carboxylic acid derivative or the 1-carbapen-2-em-3-carboxylic acid derivative derived from a 2-oxo-1-carbapenam-3-carboxylic acid derivative and trifluoromethanesulfonic anhydride, and a stannane derivative in an inert solvent in the presence of a palladium compound and a salt.
The present invention provides compounds of the formula: ##STR1## and pharmaceutically acceptable salts thereof.
本发明提供了以下式的化合物:##STR1##及其药学上可接受的盐。

and without the use of high purity reagents. The developed synthetic procedures are versatile, robust, and easily scalable. The absence of solvent, and the elimination of isolation procedures of aryl stannanes makes SSC protocol simple, step economical, and highly efficient for the synthesis of biaryls via one-pot two-step procedure.
