Compounds of the formula (I) in which R, R1 and R3 have the meanings indicated in Claim 1, are inhibitors of pyruvate dehydrogenase kinase (PDHK), and can be employed, inter alia, for the treatment of diseases such as cancer.
aldehydes and ketones has been developed using Bu4NI (TBAI) as the catalyst. In the presence of DTBP–TBHP/p-TsOH, aldehydes undergo radical coupling with ketones to provide the desired products in moderate to high yields at 120 °C. Although various substituents on the aromatic ring of aldehydes are well tolerable under the standard reaction conditions, the protocol is limited by the scope of ketones. The method
使用Bu 4 NI(TBAI)作为催化剂,已经开发了一种从醛和酮合成1,3-二酮的有效方法。在DTBP–TBHP / p -TsOH的存在下,醛与酮进行自由基偶联,从而在120°C下以中等至高收率提供所需的产物。尽管在标准反应条件下醛的芳环上的各种取代基均具有良好的耐受性,但该方案受到酮的范围的限制。该方法在起始原料容易获得,操作简单,官能团耐受性和不存在金属催化剂方面显示出优点。
Discovery of pyrazole N-aryl sulfonate: A novel and highly potent cyclooxygenase-2 (COX-2) selective inhibitors
phenyl)-1H-pyrazole-1-sulfonate exhibited excellent anti-inflammatory activity (% inhibition of auricular edemas = 27.0 and 35.9, respectively); the in vivo analgesic activity of phenyl 5-methyl-3-(p-tolyl)-1H-pyrazole-1-sulfonate and 2-chlorophenyl 5-methyl-3-(p-tolyl)-1H-pyrazole-1-sulfonate was confirmed to be effective (inhibition ratio of writhing = 50.7% and 48.5% separately), and compounds phenyl 5-
The silver‐catalyzed oxidative C(sp3)−H/P−H cross‐coupling of 1,3‐dicarbonyl compounds with H‐phosphonates, followed by a chemo‐ and regioselective C(sp3)−C(CO) bond‐cleavage step, provided heavily functionalized β‐ketophosphonates. This novel method based on a readily available reaction system exhibits wide scope, high functional‐group tolerance, and exclusive selectivity.
