Synthetic Route of 51805-45-9, Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. 51805-45-9, Name is 3,3′,3”-Phosphinetriyltripropanoic acid hydrochloride, SMILES is Cl[H].OC(=O)CCP(CCC(O)=O)CCC(O)=O, belongs to chiral-phosphine-ligands compound. In a article, author is Khong, San N., introduce new discover of the category.
Chiral aminophosphines derived from hydroxyproline and their application in allene-imine [4+2] annulation
A robust synthetic route from L-hydroxyproline (L-Hyp) to phosphines has established an expandable library of six chiral aminophosphines, which were then applied to the phosphine-catalyzed [4 + 2] allene-imine annulation. The enantioinduction in the annulations-induced by a purely steric effect-were moderate (up to 57% ee). A switch of the reaction site from the gamma- to the beta’-carbon atom of the allenoate was observed during the annulations performed using sterically demanding chiral phosphines.
Synthetic Route of 51805-45-9, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 51805-45-9 is helpful to your research.
