121463 is a potent and selective, orally active vasopressin V 2 receptor antagonist. During the synthesis of SR 121463, the formation of the stereochemistry of the cyclohexyl moiety is one of the most important steps. Conformational analysis (via NMR studies and, for cis - 3 , also via X-ray structuredetermination) of the isomers obtained in this step is reported.
