One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 1486-28-8, Name is Methyldiphenylphosphine, formurla is C13H13P. In a document, author is Zhou, Leijie, introducing its new discovery. Category: chiral-phosphine-ligands.
Direct Activation of Unmodified Morita-Baylis-Hillman Alcohols through Phosphine Catalysis for Rapid Construction of Three-Dimensional Heterocyclic Compounds
The phosphine-catalyzed tandem annulation reaction of Morita-Baylis-Hillman (MBH) alcohols with azomethine imines has been achieved for the synthesis of biologically important (ep oxymethano)-pyrazolo[5,1-b]-quinazoline derivatives. A variety of MBH alcohols and azomethine imines were well-tolerated under the mild reaction conditions, providing novel 3D heterocyclic compounds in high yields with excellent diastereoselectivities. It is the first time the direct activation of unmodified MBH alcohols acting as new oxa-synthons has been achieved.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 1486-28-8 help many people in the next few years. Category: chiral-phosphine-ligands.
