Abstract: The structure was established of all oxygen-containing compounds produced in the reaction of isocembrol, the diterpene alcohol, with aqueous formic acid in chloroform. During this cyclization, unlike the case of cembrene cyclization described previously, an earlier unknown reaction pathway is realized that results in a new stereochemical group of products with the carbon skeleton of 2,11-cyclocembrane. The presence of steric hindrances to rotation of the Δ7 double-bond moiety in the ten-membered cycle of these compounds is responsible for their existence in solutions in the form of two slowly interconverting conformers. © 1997 MAEe cyrllic signK Hayκa/Interperiodica Publishing.
