Abstract
Abstract 1. 1. Equilibrium configuration isomerization of cedrane was carried out at 563°K giving a mixture of four diastereomers of different steric configuration of methyl substituents, at C (2) and C (8) . 2. 2. The composition of the equilibrium mixture was determined 13 C NMR and mass-spectral data are given for the cedrane epimers. It established relative thermo-dynamic stability decreasing in the order of epimers: endo , exo > exo , exo > endo , endo > exo , endo .
