Cheng, Jianjun; Deming, Timothy J. published an article in 1999, the title of the article was Enantioselective polymerization of 5-benzyl glutamate N-carboxyanhydride using chiral nickel(0) initiators.Application In Synthesis of 2-(4,5-Dihydro-4,4-dimethyl-2-oxazolyl)pyridine And the article contains the following content:
Enantioselective polymerization of 5-benzyl glutamate NCA was investigated using chiral bidentate nitrogen ligands in combination with a nickel zero initiation system. We found that ligands having mixed pyridine-oxazoline structures gave excellent control of mol. weight and narrow mol. weight distributions. Moderately high enantioselectivities were induced when chiral 2-pyridinyl oxazoline ligands were utilized. The highest enantioselectivity was found with (4S)-4-tert-butyl-(2-pyridinyl)-2-oxazoline. The experimental process involved the reaction of 2-(4,5-Dihydro-4,4-dimethyl-2-oxazolyl)pyridine(cas: 109660-12-0).Application In Synthesis of 2-(4,5-Dihydro-4,4-dimethyl-2-oxazolyl)pyridine
