Two new chiral Schiff bases 1 and 2 were prepared by condensation of 3,3Ј-di-tert-butyl-5,5Ј-methylenebis(salicylaldehyde) and 3,3Ј-dimethyl-5,5Ј-methylenebis(salicylaldehyde) with (1R,2S)-(-)-2-aminodiphenylethanol and were characterized by elemental analysis, 1 H NMR,
13C NMR, IR, UV/Vis, and CD spectroscopy, optical rotation, and mass spectrometry. Highly enantioselective ring opening reactions of meso-stilbene oxide, cyclohexene oxide, cyclooctene oxide, and cis-butene oxide with anilines in the presence of several additives were carried out in the presence of Ti IV complexes generated in situ through the interaction of
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
