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. 17261-28-8, Name is 2-(Diphenylphosphino)benzoic acid, molecular formula is C19H15O2P. In a Article，once mentioned of 17261-28-8, Computed Properties of C19H15O2P
A strategy for the stereospecific construction of propionates and acetate-propionates using a directed allylic substitution was reported. The enantiomerically pure allylic o-DPPB esters having an additional oxygen functionality in the homoallylic position served as the building blocks for iterative propionate insertion. It was observed that asymmetric sharpless epoxidation of allylic alcohol followed by an epoxide ring opening with a hydride nucleophile produced the acetate-propionate structures. The process allowed the stereoselective construction of 1,5-skipped oligomethyl chains of isoprenoid or polyketide origin. Crotonaldehyde was used and treated with HCN in the presence of the oxynitrilase from bitter almonds to furnish the (R)-cyanohydrin with high levels of enantioselectivity. The nitrile function was transformed into the ethyl ester using a Pinner reaction protocol.
