Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Journal of Chromatography called Chromatographic separation of the enantiomers of 2-carboalkoxyindolines and N-aryl-α-amino esters on chiral stationary phases derived from N-(3,5-dinitrobenzoyl)-α-amino acids, Author is Pirkle, William H.; Pochapsky, Thomas C.; Mahler, George S.; Field, Richard E., which mentions a compound: 50501-07-0, SMILESS is O=C(C1NC2=C(C=CC=C2)C1)OCC, Molecular C11H13NO2, Application of 50501-07-0.
The enantiomers of N-acyl amino acid esters RNHCHR1CO2R2 (R = Ph, 1- or 2-naphthyl, 2-anthryl; R1 = Ph, Me, Et, etc.; R2 = Et, Me, etc.) and 2-carboalkoxyindolines I (R3 = R4 = H, R3 = 5-Me, R4 = 6-Me; R3 = 5-MeO, R4 = H; R3R4 = 4,5-benzo, 6,7-benzo) were separated by column chromatog. on chiral stationary phases prepared from N-(3,5-dinitrobenzoyl) derivatives of (S)-leucine or (R)-phenylglycine. The degree of chiral recognition was high. Separation factors >10 were obtained and preparative separations were performed. A chiral recognition model is presented.
