Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 850222-40-1, Name is (S)-3-(Dimethylamino)-1-(3-methoxyphenyl)-2-methylpropan-1-one, molecular formula is C13H19NO2, belongs to chiral-catalyst compound. In a document, author is Maskeri, Mark A., introduce the new discover, Category: chiral-catalyst.
Enantioselective additions to oxocarbenium ions are high-value synthetic transformations but have proven challenging to achieve. In particular, the oxa-Pictet-Spengler reaction has only recently been rendered enantioselective. We report experimental and computational studies on the mechanism of this unusual transformation. Herein we reveal that this reaction is hypothesized to proceed through a self-assembled ternary hydrogen bonding complex involving the substrate, chiral phosphate ion, and a urea hydrogen-bond donor. The computed transition state reveals C2-symmetric grooves in the chiral phosphate that are occupied by the urea and substrate. Occupation of one of these grooves by the urea co-catalyst tunes the available reactive volume and enhances the stereoselectivity of the chiral phosphate catalyst.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law. In my other articles, you can also check out more blogs about 850222-40-1. Category: chiral-catalyst.
