Acid-catalyzed rearrangement of 3,3,3',3'-tetramethyl-1,1'-bi(cyclobutylidene) (8) results in the formation of (3aR*,6aR*)-2,2,5,6-tetramethyl-1,2,3,3a,4,6a-hexahydropenta lene [(3aR*,6aR*)-9], a potential precursor of protoilludane sesquiterpenes. Compound 8 is prepared by oxidation and in situ coupling of cyclobutylidene-phosphorane 7.
