“…Ketone 11 was catalytically reduced (Pt02, H2) to alcohol 12, which was isolated as colorless crystals. The 13C NMR spectrum of 12 exhibited the theoretical number of peaks, so the reduction was presumed to be stereospecific. (For 100-MHz NMR spectral data, see supplementary material.)…”

“…Compound 13 was prepared in crystalline form by methylation of alcohol 12 with trimethyloxonium tetrafluoroborate in CH2C12. The 100-MHz NMR spectrum of 13 exhibited the same extensive overlap of the ring proton resonances as did that of compound 12. (See supplementary material, Figures 1 and 2, for 300-MHz NMR spectral data.)…”

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.
