Organotin-catalyzed synthesis of hydroxyalkylamides from lactones via a ring-opening process was written by Liang, Xiayu;Yu, Peng;Fu, Chen;Shen, Yongcun. And the article was included in Tetrahedron Letters in 2021.Application In Synthesis of 5-Ethyldihydrofuran-2(3H)-one This article mentions the following:
A new strategy for the facile synthesis of hydroxyalkylamides through the ring-opening reaction of lactones with amine promoted by dibutyltin acetate was developed. A series of hydroxyalkylamide compounds were obtained and the method was successfully applied to the synthesis of pharmaceutically active mols. tyrosinase inhibitor V and HDAC inhibitor VI via a three-step synthetic pathway. The broad substrate scope, mild reaction conditions and practical application proved the effectiveness, compatibility and practicality of this method. In the experiment, the researchers used many compounds, for example, 5-Ethyldihydrofuran-2(3H)-one (cas: 695-06-7Application In Synthesis of 5-Ethyldihydrofuran-2(3H)-one).
5-Ethyldihydrofuran-2(3H)-one (cas: 695-06-7) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is 绾?valerolactone.Application In Synthesis of 5-Ethyldihydrofuran-2(3H)-one
