Jl. Coudret et al., ROLE OF CYCLOPROPANES AS ACTIVATING GROUPS DURING OXIDATION REACTIONSWITH RUO4 GENERATED IN-SITU, Tetrahedron letters, 37(14), 1996, pp. 2425-2428
Ruthenium tetroxide generated in situ under the Sharpless conditions w
as applied to different hydrocarbons containing cyclopropane groups ei
ther spiroanellated or ring-fused. In all cases oxidation occurred exc
lusively at the positions alpha to the cyclopropyl group to give keton
es. Ring cleavage was observed when such positions were tertiary. Copy
