Witt, Anette; Gustavsson, Annika; Bergman, Jan published their research in Journal of Heterocyclic Chemistry on February 28 ,2003. The article was titled 《Studies towards the synthesis of the benzodiazepine alkaloid auranthine. Synthesis of an acetylated derivative》.Category: piperidines The article contains the following contents:
Different approaches towards the synthesis of auranthine have been investigated. A completed synthesis of 3-[2-(4-oxo-3,4-dihydro-quinazolin-2-yl)-ethyl]-3,4-dihydro-1H-benzo[e][1,4]-diazepine-2,5-dione I, an auranthine precursor, which after dehydration with 50% propylphosphonic acid anhydride solution in Et acetate and DMA gave a C-acetyl derivative of auranthine. Addnl. studies towards the synthesis of fused quinazolinones yielded the C-acetylated pyrido[2,1-b]quinazolinones or butyric acid derivatives In the part of experimental materials, we found many familiar compounds, such as Benzyl (2,6-dioxopiperidin-3-yl)carbamate(cas: 24666-55-5Category: piperidines)
Benzyl (2,6-dioxopiperidin-3-yl)carbamate(cas: 24666-55-5) belongs to anime. Hydrogen peroxide (H2O2) and peroxy acids generally add an oxygen atom to the nitrogen of amines. With primary amines, this step is normally followed by further oxidation, leading to nitroso compounds, RNO, or nitro compounds, RNO2. Secondary amines are converted to hydroxylamines, R2NOH, and tertiary amines to amine oxides, R3NO.Category: piperidines
