The stereochemistry around the N‐benzoylated indole moiety of indometacin was studied by restricting the rotation about the NC7′ and/or C7′C1′ bond. In the 2′,6′‐disubstituted ones, an atropisomericproperty was found and the atropoisomers were separated and isolated as stable forms. Their biological abilities to inhibit cyclooxygenase‐1 (COX‐1) and cyclooxygenase‐2 (COX‐2) were examined. Only the
N-benzoylated carbazole derivatives were investigated. It was found that the bulky t-butyl and iodo groups restricted rotation about the N–C7′ and C7′–C1′ bonds to separate four stereoisomers, in which rotation about the C7′–C1′ bond was in perfect concert with rotation about the N–C7′ bond. The relation of the rotation of the N–C7′ and C7′–C1′ axes was investigated by comparing the stereochemistry of
The stereochemistry of N-benzoylated pyrroles and imidazoles was studied. 2,6-Disubstituted 1-benzoypyrroles and 1-benzoylimidazoles were shown to have an atropisomeric property and their stable atropisomers were isolated.
