A novel and efficient approach for the regioselective selenylation of 4H-pyrido-[1,2-a]-pyrimidin-4-ones with diselenides at room temperature was developed. This procedure was catalyzed by N-iodosuccinimide under metal-free conditions with a broad range of substrate scopes and affords C3 selenylation products in good to excellent yields. Furthermore, the sulfenylation with di-Ph disulfides and 4-methylbenzenethiol in this transformation was successful. In the experiment, the researchers used many compounds, for example, Ethyl 3-oxo-3-(m-tolyl)propanoate (cas: 33166-79-9Application In Synthesis of Ethyl 3-oxo-3-(m-tolyl)propanoate).
Ethyl 3-oxo-3-(m-tolyl)propanoate (cas: 33166-79-9) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Application In Synthesis of Ethyl 3-oxo-3-(m-tolyl)propanoate
