✦ Synopsis

Abstract

Several C^9^‐carbamoyl derivatives of quinine have been prepared and compared as chiral solvating agents in NMR enantiodiscrimination experiments of amino acid derivatives. The origin of the enantiodiscrimination phenomena was identified by NMR conformational analysis of the chiral auxiliaries and investigations of solution complexation phenomena.(© Wiley‐VCH Verlag GmbH & Co.

The locus of the photodimerization reaction of 9-methylanthracene in the crystal was examined by high-resolution solid-state 13C NMR techniques. Examination of the 13C spectra of the products showed that only the trans dimer is formed by the solid state photodimerization, while both trans and cis di
