The alkylation of the amides of dehydroabietic acid
New frontiers in natural product chemistry, 2023 In this abstract is being discussed the synthesis of new substituted amides of dehydroabietic acid with different bromides in system K2CO3/DMF. It is known fact that many compounds, such as famous isatine 1, have the amide group in its molecule. There is no point in talking about it, because everything is known regarding chemical properties.
