Abstract

The structures of olivoretin B and C were established by X-ray analysis as III and IV respectively. In the crystal olivoretin C was a random mixture of conformers A and B existing in the ratio of 1 : 1. The two conformers in the crystal are concerned with the cyclohexene ring conformation.
