A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 39648-67-4, Name is (R)-4-Hydroxydinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepine 4-oxide, molecular formula is C20H13O4P. In a Article，once mentioned of 39648-67-4, Application In Synthesis of (R)-4-Hydroxydinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepine 4-oxide
A synergistic rhodium(II)/phosphoric acid catalyzed three component reaction of 3-diazooxindoles, alcohols and N-benzhydryl-alpha-imino ester is developed for the efficient construction of chiral beta-alkoxy Cbeta-tetrasubstituted alpha-amino acid derivatives in good yields and with excellent diastereoselectivities and high enantioselectivities. The synthetic application of the resulting products was illustrated by reducing with Pd/C under H2atmosphere followed reacting with CSCl2at room temperature to rapid afford 3-spirocyclic oxindole in a good yield with a chirality retainment. The three-component reaction is proposed to proceed through an electrophilic trapping of the oxonium ylides by N-benzhydryl-alpha-imino ester.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Application In Synthesis of (R)-4-Hydroxydinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepine 4-oxide.
