Mercado-Marin, Eduardo V.; Chheda, Pratik Rajesh; Faulkner, Andrea; Carrera, Diane published the article 《Magnesium ethoxide mediated lactone aminolysis with aminoheterocycles》. Keywords: aromatic amine lactone aminolysis reaction; amino amide preparation.They researched the compound: (R)-4-Hydroxydihydrofuran-2(3H)-one( cas:58081-05-3 ).Name: (R)-4-Hydroxydihydrofuran-2(3H)-one. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:58081-05-3) here.
A mild method for the aminolysis of lactones with aminoheterocycles in the presence of magnesium ethoxide was described. A wide range of electronically diverse aminoheterocycles and substituted lactones successfully participated in this transformation to furnish the resulting amido-alc. products. Further application of this method to the synthesis of chiral α-amino amides derivatives was also described.
When you point to this article, it is believed that you are also very interested in this compound(58081-05-3)Name: (R)-4-Hydroxydihydrofuran-2(3H)-one and due to space limitations, I can only present the most important information.
