Quality Control of Ethyl 3-oxopentanoate The article mentions the following:
One-step synthesis of 9-anthrone lactone derivatives from 1-acetyloxyanthraquinone with a variety of dicarbonyl substrates in the presence of K2CO3 by Knovenagel condensation and intramol. cyclization is developed. Possible reaction mechanisms have been investigated using the d. functional theory (DFT), which has been widely used in the study of reaction mechanism. The strategy could be useful for the synthesis of the core structure of marine natural product aspergiolide. In the experiment, the researchers used many compounds, for example, Ethyl 3-oxopentanoate(cas: 4949-44-4Quality Control of Ethyl 3-oxopentanoate)
Ethyl 3-oxopentanoate(cas: 4949-44-4) belongs to ketone compounds. Ketones are highly reactive, although less so than aldehydes, to which they are closely related. Much of their chemical activity results from the nature of the carbonyl group. Ketones readily undergo a wide variety of chemical reactions.Quality Control of Ethyl 3-oxopentanoate
