A direct synthesis of highly functionalized 2-alkylcarbapenems via a palladium-catalyzedcross-couplingreaction of alkylboranes with carbapenem-2-yl triflates is described. An advantage of this procedure is the introduction of C-2 alkyl side chain at the later stage of the synthesis, thus allowing the syntheses of a wide variety of functionalized 2-alkylcarbapenems more accessible.
