ic acid (4) was conveniently synthesised from 3-fluorobenzaldehyde in six steps. The structure of this new compound and three other intermediates, 3-fluorophenylcyanoethylacrylate (1), 3-fluorophenyl succinic acid (2) and 6-fluoro-3-oxo-indan-1-carboxylic acid (3) was elucidated by comprehensive spectral data analyses. The analgesic activity of compounds 3 and 4 was assessed by the acetic acid induced

This application discloses CD73 inhibitors represented by the general formula (I) and analogs thereof, pharmaceutical compositions containing these compounds, methods of preparing them, and use of these compounds as therapeutic agents for the treatment of diseases or conditions associated with CD73 activity, such as various cancers.
The catalytic regio- and enantioselective hydrocarboxylation of alkenes with carbon dioxide is a straightforward strategy to construct enantioenriched α-chiral carboxylic acids but remains a big challenge. Herein we report the first example of catalytic highly enantio- and site-selective remote hydrocarboxylation of a wide range of readily available unactivated alkenes with abundant and renewable CO2
烯烃与二氧化碳的催化区域和对映选择性加氢羧化是构建对映体富集的 α-手性羧酸的简单策略,但仍然是一个巨大的挑战。在此,我们报告了在 SaBOX/Ni 催化剂的温和条件下,利用丰富且可再生的 CO 2对各种容易获得的未活化烯烃进行高度对映和位点选择性远程加氢羧化的催化例子。这一成功的关键是利用手性 SaBOX 配体,它与镍结合,同时控制链行走和羧化的对映选择性。该方法以高产率和区域选择性和对映选择性直接提供一系列带有各种官能团的不同烷基链取代或苯并稠合的 α-手性羧酸。此外,通过从商业起始材料中简明合成抗血小板聚集药物( R )-吲哚布芬,证明了该方法的合成效用。
