通过DABCO催化的1,4-萘醌衍生物,α,β-不饱和酮和水合硫化钠的三组分反应,已经开发了萘并[2,3 - b ]噻吩-4,9-二酮的有效合成方法。通过依次向α,β-不饱和酮中添加硫化钠,并向1,4-萘醌衍生物中生成阴离子,依次进行迈克尔的加成反应,然后进行分子内氧化环化和芳构化,来引发反应。在反应条件下,α,β-不饱和酮中的各种官能团得以存活,并且以高收率产生了萘并[2,3 - b ]噻吩-4,9-二酮。
3-b]furan-4,9-diones has been developed by N-iodosuccinimide (NIS)-induced enone difunctionalization with 2-hydroxy-1,4-naphthoquinones. This reaction involved sequential Michael addition, intramolecular oxidative cyclization and dehydrogenative aromatization to form new C–C and C–O bonds at the α and β positions of the enones. Various enones survived under the reaction conditions and the corresponding products
isolate as well. In silico analysis of ADMET properties showed that the evaluated chalcones displayed satisfactory pharmacokinetic parameters. In conclusion, the obtained data demonstrate that at least two of the studied chalcones, compounds 4 and 5, are promising antimycobacterial and anti-inflammatory agents, especially focusing on an anti-tuberculosis dual treatment approach.

A new series of 3‐substituted 4‐(4‐methyloxy phenyl)‐1H‐pyrrole derivatives were synthesized and biologically evaluated for potential anticancer activity. Fifteen targeted compounds showed high selectivity toward normal cells and cancer cells: that is, all targeted compounds had no obvious cytotoxicity toward normal human cells (HUVEC and NIH/3T3), but some compounds exhibited broad‐spectrum proliferation
