By the action of LDA bicycloC4.4.llundeca-1(10),2,4,8-tetraen-1 l-one was found to undergo transannular cyclization to form a unique tricyclic hydroxydihydroozulene which cleaves a C-C bond by Cn8s+u2251 electrocyclic process and eventually give 4-methylazulene.

An unusual C-C bond length (1.81 A) is observed in a derivative of [ 101 annulrne; a possibility of cocsistence of two different isomers in the same crystal structure is definitely ruled out by a lattice-dynamical analysis of thermal motion.
