硝基(杂)芳烃衍生物是用于各种产品(例如药物、聚合物和农用化学品)的重要商品化学品。在这项研究中,我们利用铜催化剂和硝基(杂)芳烃的激发态反应性以及酰基自由基的反极性反应性,将容易获得的硝基(杂)芳烃直接转化为有价值的2-氨基苯酚衍生物,这是许多领域的重要支架。最畅销的药品。该反应适用于多种硝基(杂)芳烃、酰氯以及复杂分子的后期修饰,使其成为发现新功能分子的有用工具。机理研究,包括自由基捕获实验、Stern Volmer 猝灭研究、光开/关实验和 O 标记研究,表明反应机制涉及铜配合物的光激发、双自由基耦合和笼内接触离子对迁移。我们的研究结果提供了一种简化的方案,用于从硝基(杂)芳烃合成基本药效团,同时推进激发态和自由基化学的知识并刺激新的反应设计和开发。

A series of phenoxy benzoxaboroles were synthesized and screened for their inhibitory activity against PDE4 and cytokine release. 5-(4-Cyanophenoxy)-2,3-dihydro-1-hydroxy-2,1-benzoxaborole (AN2728) showed potent activity both in vitro and in vivo. This compound is now in clinical development for the topical treatment of psoriasis and being pursued for the topical treatment of atopic dermatitis. (C) 2009 Elsevier Ltd. All rights reserved.

The 3-benzimidazol-2-yl-1H-indazole scaffold was developed as an alternate scaffold for our receptor tyrosine kinase (RTK) inhibitor program. In exploring the SAR of this series, it was discovered that a subset of these compounds potently inhibit the enzyme c-ABL. The SAR of these compounds is described. (c) 2006 Elsevier Ltd.
