Onimura, Kenjiro published the artcileAsymmetric polymerization of N-substituted maleimides with organolithium-bisoxazolines complex, Application of (4S,4’S)-4,4′-Diisobutyl-4,4′,5,5′-tetrahydro-2,2′-bioxazole, the publication is Polymer Bulletin (Berlin) (1997), 39(4), 437-444, database is CAplus.
Asym. anionic polymerizations of achiral N-substituted maleimide (RMI) (N-cyclohexyl, N-Ph, and N-tert-Bu) by n-butyllithium (n-BuLi) or fluorenyllithium (FlLi) complexes of chiral bisoxazoline derivatives in toluene gave optically active polymers ([α]43525 -2.9 to -8.2°). The polymers prepared with initiator of n-BuLi-2,2′-bis(4,4′-isopropyl-1,3-oxazoline) showed neg. sp. rotations (poly(RMI), [α]43525 -5.8 to -8.2°) which were greater than those ([α]43525 -2.9 to -5.9°) with other chiral 2,2′-bis(4,4′-alkyl-1,3-oxazoline) (alkyl = iso-Bu and benzyl).
Polymer Bulletin (Berlin) published new progress about 138429-17-1. 138429-17-1 belongs to oxazolidine, auxiliary class BOX Ligands, name is (4S,4’S)-4,4′-Diisobutyl-4,4′,5,5′-tetrahydro-2,2′-bioxazole, and the molecular formula is C14H24N2O2, Application of (4S,4’S)-4,4′-Diisobutyl-4,4′,5,5′-tetrahydro-2,2′-bioxazole.
