Cyclopropanation of tricyclo[5.2.1.0(2,6)]deca-2(6),8-dien-3-one using dimethylsulfoxonium ylide gave a highly strained annotated cyclopropane in 68% yield with complete exo-face selectivity. Nucleophilic epoxidation gave a strained epoxide in 68% yield, again completely exo-face selective. Surprisingly, using methanol as the co-solvent in this epoxidation yielded a disubstituted tricyclodecenone in 85% yield instead of the epoxide. This result can be explained by a Payne-type rearrangement of the initially formed epoxide. (C) 2008 Published by Elsevier Ltd.
