Organocatalytic Enantioselective Amination of 2-Substituted Indolin-3-ones: A Strategy for the Synthesis of Chiral α-Hydrazino Esters was written by Yarlagadda, Suresh;Ramesh, B.;Ravikumar Reddy, C.;Srinivas, L.;Sridhar, B.;Subba Reddy, B. V.. And the article was included in Organic Letters in 2017.COA of Formula: C7H8N2O2 This article mentions the following:
An efficient enantioselective α-amination of 2-substituted 3-indolinones has been achieved for the first time using hydroquinidine as a chiral catalyst through an aza-Michael reaction. The desired α-hydrazino esters were obtained in excellent yields with high enantiomeric excess leading to a quaternary stereocenter with a broad substrate scope. In the experiment, the researchers used many compounds, for example, Methyl 2-aminonicotinate (cas: 14667-47-1COA of Formula: C7H8N2O2).
Methyl 2-aminonicotinate (cas: 14667-47-1) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.COA of Formula: C7H8N2O2
