Abstract

When as many as four vicinal couplings occur between four protons situated on three carbon atoms of a cyclobutane ring, one can employ the Karplus relation to assign the configuration of substituents at the remaining positions and make some inferences about the stereochemistry. Four examples are described; the spectra and data are analyzed.
