nylsulphonyl-chloro-quinoxaline 1,4-dioxides belonging to series 3-6 were synthesised and submitted to a preliminary in vitro evaluation for antimycobacterial, anticandida and antibacterial activities. Antitubercular screening showed a generally good activity of 3-methyl-2-phenylthioquinoxaline 1,4-dioxides (3d,e,h-j) against Mycobacterium tuberculosis, and exhibited MIC between 0.39 and 0.78 microg

including more than 60 compounds, were prepared. In the first one, the benzotriazole moiety was linked through the nitrogen atoms 1, 2, or 3, to a glutaric acid substituent to simulate a glutamic moiety. In the second series, the glutaric acid was substituted with acetic acid moiety to evaluate the effects of steric hindrance. Here, we describe the multistep chemical processes to obtain all titled quinoxalines

A new quinoxaline1,4-dioxide benzylsulfanyl derivative was tested under mild conditions in copper-mediated Liebeskind–Srogl (LS) cross-coupling reactions with arene boronic acids. These first organometallic cross-coupling reactions performed on a quinoxaline1,4-dioxidederivative open new perspectives in medicinal chemistry. They represent also the first LS cross-couplings run with an electrophile
在铜介导的 Liebeskind-Srogl (LS) 与芳烃硼酸的交叉偶联反应中,在温和条件下测试了一种新的喹喔啉 1,4-二氧化物苄基硫烷基衍生物。这些对喹喔啉 1,4-二氧化物衍生物进行的首次有机金属交叉偶联反应为药物化学开辟了新的视角。它们还代表了第一次使用配备芳基 N-氧化物部分的亲电子试剂运行的 LS 交叉偶联。
