چکیده انگلیسی
Fragmentation by potassium hydroxide of non-enolisable β-mesyloxy-cyclopentanones fused to a cyclopropane ring in αâ²,βâ²-positions proceeds efficiently from derivatives possessing (i) an exo-mesyloxy group and an endo-methyl group on the cyclopropane ring and (ii) an endo-mesyloxy group and an endo-hydrogen on the cyclopropane ring. This reactivity has been tentatively correlated to an antiperiplanar arrangement of atoms and bonds involved in the process accessible from various stereoisomers owing the flexibility of the five-membered ring.
