β-lactamase inhibitors and today several β-lactamase inhibitors e.g. avibactam, are approved in the clinic. Our focus is the oxacillinase-48 (OXA-48), an enzyme reported to spread rapidly across the world and commonly identified in Escherichia coli and Klebsiella pneumoniae. To guide inhibitor design, we used diversely substituted 3-aryl and 3-heteroaryl benzoic acids to probe the activesite of OXA-48

The rapidly prepared 1,3‐diaminobenzene‐derived aminophosphine pincer complex C6H3[NHP(piperidinyl)2]2Pd(Cl)} (1) is an effective Suzuki catalyst with excellentfunctionalgrouptolerance. Side‐product formations, such as homocoupling, debromation or protodeboration have only rarely been detected and if so, were in all cases below the 5% level. The presented reaction protocol is universally applicable
快速制备的1,3-二氨基苯衍生的氨基膦钳形配合物C 6 H 3 [NHP(哌啶基)2 ] 2 Pd(Cl)}(1)是一种有效的Suzuki催化剂,具有出色的官能团耐受性。仅很少检测到副产物形成,例如均偶联,去溴化或原去硼,如果这样,在所有情况下均低于5%的水平。提出的反应方案是普遍适用的。实验观察表明,钯纳米颗粒的催化活性形式1。
