Palladium-catalyzed oxidativeamidation has been used to synthesize hydroxamic acid-containing bicyclic β-lactam cores. Oxidative cleavage of the pendant alkene provides access to the carboxylic acid in one step.
钯催化的氧化酰胺化已用于合成含异羟肟酸的双环β-内酰胺核。侧链烯烃的氧化裂解可一步一步获得羧酸。

With antibiotic resistance on the rise, the need for new medicinal scaffolds is needed. The synthesis of an aminal bicyclic beta-lactam core is described. The key synthetic step is Pd(II)-catalyzed oxidative amidation. The product is a single diastereomer, confirmed by X-ray crystallography. (C) 2014 Elsevier Ltd. All rights reserved.
