摘要

2, 3-Dimethylene-7-oxabicyclo [2.2. 1] heptane, available by reduction and dehydration of the furan-fumaroyl chloride Diels-Alder adduct, undergoes ready dibromocyclopropanation at one of its exocyclic double bonds. The corresponding carbenoid, generated by reaction of the dibromide wilh 4 equiv of an organolithium reagent, undergoes the Skattebøl rearrangement to provide a fused cyclopentadiene ring which is immediately ...
