The stereospecific synthesis of a series of model compounds for N-substituted maleimide/vinyl ether alternating copolymers is described. The stereochemistry of the compounds prepared could be unambiguously deduced via utilization of 1H NMR coupling constants. Comparison of the 13C NMR chemical shifts of the model compounds with those of the copolymers suggests that the predominant stereochemistry at the succinimide units in the copolymers is erythro. A detailed comparison of the several properties of the copolymers with those of the model compounds is reported in an accompanying paper.
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.
