Vinyl-triflates and related 3-substituted cephems readily undergo addition-elimination reactions with a variety of organocuprates to form new carbon-carbon bonds. This chemistry presents a novel approach to the synthesis of 3-alkyl, 3-aryl, and 3-alkenylcephalosporins.
乙烯基三氟甲磺酸酯和相关的3-取代的头孢很容易与各种有机铜化合物进行加成消除反应,以形成新的碳-碳键。该化学方法提供了一种合成3-烷基,3-芳基和3-烯基头孢菌素的新颖方法。
