Isatin je organická sloučenina, derivát indolu. Poprvé ji připravili roku 1840 Otto Linné Erdmann a Auguste Laurent oxidací indiga kyselinou dusičnou a kyselinou chromovou. Isatin se nachází v mnoha rostlinách, jako jsou boryt barvířský, Calanthe discolor a Couroupita guianensis.
The analysis highlights Reakce, Overview and Příprava as prominent areas in the source structure around Isatin.
Source areas are shown by the number of related topics found in each part of the analysis. Use smaller areas too: they can reveal specialized angles and content gaps.
Smaller areas are not necessarily less important. They contain fewer connections in this analysis and can be useful for finding specialized angles or coverage gaps.
