Yabuuchi, Tetsuya published the artcileApplication of phenylglycine methyl ester (PGME) to determination of the absolute configuration of carboxylic acids having phenylalkyl group, COA of Formula: C11H14O2, the publication is Chirality (1997), 9(5/6), 550-555, database is CAplus.
(S)-phenylglycine Me ester [(S)-PGME] was applied to elucidate the absolute configuration of a series of aliphatic carboxylic acids Ph(CH2)nCHRCO2H (I; n = 1-6; R = Me, Et) which possess a Ph group on the chain, by the process similar to the modified Mosher’s method. (S)-PGME was condensed with rac-I, and the resulting diastereomeric pair was separated ¦¤¦Ä Values were calculated from the 1H-NMR chem. shifts of the diastereomeric PGME amides. By analyzing the pos. and neg. distribution patterns for each compound, it was concluded that this new method was successful to predict the absolute configuration of such type of acids, and that no significant interaction between the two Ph groups, one in the chain and the other in the PGME, was present.
Chirality published new progress about 1949-41-3. 1949-41-3 belongs to catalysis-chemistry, auxiliary class Carboxylic acid,Benzene, name is 2-Methyl-4-phenylbutanoic acid, and the molecular formula is C15H10O2, COA of Formula: C11H14O2.
