  Facile Preparation of 3,4-Benzocoumarins from 2-Arylbenzoic Acids with NCS and Nai

  摘要：

  Treatment of 2-arylbenzoic acids with N-chlorosuccinimide (NCS) and NaI at 70 degrees C under fluorescent lighting condition gave the corresponding 3,4-benzocoumarins in good yields under transition-metal-free condition. It was found that the reactivity of NCS with NaI for the formation of 3,4-benzocoumarins from 2-arylbenzoic acids was as high as that with NIS. Thus, the formation of carboxyl radicals and their cyclization onto an aromatic ring from 2-arylbenzoic acids with much less expensive NCS and NaI, than NIS could be successfully carried out to form 3,4-benzocoumarins.

  Screening of a part of the BASF library against the PfIspD enzyme led to the identification of a pyrrole as an underexplored chemical scaffold that is able to target the third enzyme in the MEP pathway. A detailed structure–activity relationship (SAR) study around the fragment hit compound helped us to successfully improve the potency as well as the physicochemical properties.

  针对Pf IspD 酶对巴斯夫文库的一部分进行筛选，结果发现吡咯是一种尚未开发的化学支架，能够靶向 MEP 途径中的第三种酶。围绕片段命中化合物进行的详细构效关系 (SAR) 研究帮助我们成功提高了效力和理化性质。

  The N-tosylcarboxamide group offers the possibility of directing the Pd-catalyzed C–H arylation of arenes providing a new entry to biarylcarboxamides. Moreover, its ability to react according to different reaction conditions including intramolecular reactions makes it a pivotal directing group for a divergent synthesis of biaryl-based compounds.
