A series of substituted-nicotinyl thioureaderivativescontainingpyrimidinering were synthesized in good to excellent yield using PEG-400 as solid–liquid phasetransfer catalyst underultrasonicirradiation. The structures of all newly synthesized compounds were elucidated and confirmed by IR, 1H NMR and elemental analysis. The preliminary biological tests show that some of the target compounds present
在超声辐射下,使用PEG-400作为固液相转移催化剂,合成了一系列含有嘧啶环的取代烟酰胺基硫脲衍生物,收率良好。通过IR,1 H NMR和元素分析阐明并确认了所有新合成的化合物的结构。初步的生物学测试表明,某些目标化合物对双子叶植物的根和茎具有良好的抑制活性,对单子叶植物是安全的。

A series of substituted acyl(thio)urea and 2H-1,2,4-thiadiazolo [2,3-a] pyrimidine derivatives were prepared and both of their cell culture and enzymatic activity toward influenza virus were tested. Their in vitro neuraminidase inhibitory activities were in good agreement with the corresponding activities in cultured cells and they were evaluated as potent neuraminidase inhibitors. Of the analogues

H2S‐Abspaltung zu den 3‐Amino‐thioacrylsäure‐O‐estern 11. Die Alkalisalze von 1 setzen sich mit Aminen unter. Alkohol‐Eliminierung zu den Malondithioamiden 12 um. Durch oxidative Ringschluß erhält man aus 11 die Isothiazole 16–18. Die Kondensation von 1 mit Hydrazinen liefert die Pyrazole 20–22; mit Amidinen entstehen die Pyrimidine 23 und 24.
