A direct synthesis of highly functionalized 2-alkylcarbapenems via a palladium-catalyzed cross-coupling reaction 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.
描述了通过烷基硼烷与碳青霉烯-2-基三氟甲磺酸酯的钯催化的交叉偶联反应直接合成高度官能化的2-烷基碳烯属化合物。该方法的一个优点是在合成的后期引入C-2烷基侧链,从而使各种官能化的2-烷基碳烯化合物的合成更容易获得。
