I found the field of Chemistry very interesting. Saw the article 5-endo-dig Cyclization of O-Propargyl Mandelic Acid Amides towards 2,5-Dihydrofurans published in 2019.0. Recommanded Product: 3-Pyridinecarboxaldehyde, Reprint Addresses Fincias, N; Garrec, J; El Kaim, L (corresponding author), Inst Polytech Paris, LSO, Ecole Polytech, CNRS,ENSTA Paris UMR 7652, 828 Bd Marechaux, F-91128 Palaiseau, France.. The CAS is 500-22-1. Through research, I have a further understanding and discovery of 3-Pyridinecarboxaldehyde
5-endo-dig cyclization of O-propargyloxyamides, obtained through a Passerini reaction mediated by boric acid and subsequent propargylation, affords 2,5-dihydrofurans in the presence of tert-butylate. The mechanism of the reaction was studied by using DFT calculations and the results were compared with the behavior of analogous N-propargylamide derivatives.
Recommanded Product: 3-Pyridinecarboxaldehyde. Welcome to talk about 500-22-1, If you have any questions, you can contact Ben Gaied, L; Fincias, N; Garrec, J; El Kaim, L or send Email.
