Embodiments concern methods and small molecule compositions for selectively inhibiting RAD51-mediated D-loop formation while preserving RAD51's ability to form nucleoprotein filaments. The selective RAD51 D-loop formation activity inhibitors DNA repair while minimizing replication-associated toxicity in normal tissue.

A convenient Pictet-splengler approach for the synthesis of substituted pyrrolo[1,2-a]quinoxaline from aryl amines and 1-(2-aminoaryl)-pyrrole has been developed. This is the first domino protocol involving formation of benzaldehyde as an intermediate from benzyl amines and benzyl alcohols using 1,2-DNB as an oxidant, followed by its endo cyclization with 1-(2-aminophenyl)-pyrrole to furnish the pyrrolo[1
Green palladium-catalyzed nitroarene/nitrile reductive cross-annulation chemistry that facilitates straightforward access to pyrrolo[1,2-a]quinoxaline derivatives is described herein. A range of nitriles are activated as carbon synthons to form intramolecular CN and CC bonds using this chemistry. The synthetic protocol has the advantages of broad substrate scope, excellent functional group tolerance
本文描述了绿色钯催化的硝基芳烃/腈还原交叉环化化学,它有助于直接获得吡咯并 [1,2-a] 喹喔啉衍生物。使用这种化学方法,一系列腈被激活为碳合成子,形成分子内 C N 和 C C 键。该合成方案具有广泛的底物范围、优异的官能团耐受性以及使用环保水和廉价的 HCOONa/HCOOH 分别作为溶剂和氢供体的优点。该催化剂可方便地通过过滤回收,至少可以重复使用五次而不会出现明显的失活。这项研究为将散装化学基序转化为增值功能框架提供了一个重要平台。
