Abstract

The bis-trimethylsilyl-bicyclo [n, 1, 0] 2-alkene antioxides (n= 4 and 6) have been synthesized from their 1, 3-diene precursors by a three-step process ( dichlorocyclopropanation, silylation, and epoxidation). Their rearrangement in the presence of solid and liquid Lewis acids was studied, and compared with the previously described reactivity of 2-carene oxide. With these silylated epoxides, the breaking of the C3-O bond ...
