15 صفحه اولAn oxidative amidation and heterocyclization approach for the synthesis of β-carbolines and dihydroeudistomin Y
A novel synthetic methodology has been developed for the synthesis of dihydro-β-carboline derivatives employing oxidative amidation-Bischler-Napieralski reaction conditions using tryptamine and 2,2-dibromo-1-phenylethanone as key starting materials. A number of dihydro-β-carboline derivatives have been synthesized in moderate to good yields using this methodology. Attempts were made towards the...
متن کاملOxidative polymerization of lignins by laccase in water-acetone mixture.
The enzymatic oxidative polymerization of five technical lignins with different molecular properties, i.e. Soda Grass/Wheat straw Lignin, Organosolv Hardwood Lignin, Soda Wheat straw Lignin, Alkali pretreated Wheat straw Lignin, and Kraft Softwood was studied. All lignins were previously fractionated by acetone/water 50:50 (v/v) and the laccase-catalyzed polymerization of the low molecular weig...
