A series of spirocyclic analogues as potent inhibitors of bacterial phenylalanyl- t RNA synthetases
摘要:
We have identified a series of spirocyclic furan and pyrrolidine inhibitors of Enterococeus faecalis and Staphylococcus aureus phenylalanyl-tRNA synthetases. The most potent analogue 1b showed IC50 = 5 nM (E. faecalis PheRS) and IC50 = 2 nM (S. aureus PheRS) with high selectivity over the human enzyme. The crystal X-ray structure of analogue 1b was determined. (C) 2004 Elsevier Ltd. All rights reserved.

Fullerene C70 as Photoredox Catalyst for the Synthesis of Pyrrolo[2,1‑a]isoquinolines via 1,3‐Dipolar Cycloaddition‐Aromatization Sequence
Metal-free photoredox catalyst C70 was introduced for the facile construction of pyrrolo[2,1-a]isoquinolines under mild conditions, yielding a diverse library of pyrrolo[2,1-a]isoquinolines. Low catalyst loading, gram scale synthesis, and broad substrate scope (48 examples) demonstrate the synthetic utility of the protocol and encourage its future application as a photoredox catalyst in organic transformations
引入无金属光氧化还原催化剂 C 70以在温和条件下轻松构建吡咯并 [2,1-a] 异喹啉,产生多样化的吡咯并 [2,1-a] 异喹啉库。低催化剂载量、克级合成和广泛的底物范围(48 个例子)证明了该协议的综合效用,并鼓励其在未来作为光氧化还原催化剂在有机转化中的应用。
