  摘要：

  Replacement of the core heterocycle of a defined series of chromen-4-one DNA-PK inhibitors by the isomeric chromen-2-one (coumarin) and isochromen-1-one (isocoumarin) scaffolds was investigated. Structure-activity relationships for DNA-PK inhibition were broadly consistent, albeit with a reduction of potency compared with the parent chromenone. (C) 2010 Elsevier Ltd. All rights reserved.

  Abstract A novel and convenient protocol for the synthesis of sulfonate derivatives via DABCO-catalyzed direct sulfonylation of 1-sulfonyl-1,2,3-triazoles to different enols has been established. This synthetic route could effectively avoid the use of transition metal catalysts and extra oxidants, and the target products could be obtained in good to excellent yields (75-86%) with wide substrate scope

  摘要 建立了一种通过 DABCO 催化的 1-磺酰基-1,2,3-三唑直接磺酰化为不同烯醇合成磺酸盐衍生物的新型便捷方案。该合成路线可以有效地避免使用过渡金属催化剂和额外的氧化剂，在温和条件下，低催化剂负载量下可以以良好到优异的收率（75-86％）获得目标产物，具有广泛的底物范围，这将提供轻松实用地获得烯醇磺酸盐。此外，通过 Suzuki-Miyaura、Sonogashira 和 Heck 交叉偶联反应证明了使用所得烯醇磺酸盐形成 CC 键。图形概要
