Abstract
Acid-catalyzed rearrangement of 3,3,3',3'-tetramethyl-1,1 '-bi(cyclobu tylidene) (8) results in the formation of 2,5,6-tetramethyl-1,2,3,3a,3 ,6a-hexahydropentalene [(3aR,6aR*)-9], a potential precursor of proto illudane sesquiterpenes. Compound 8 is prepared by oxidation and in si tu coupling of cyclobutylidenephosphorane 7.
