Abstract

Summary: Lithium phenylthio [2, 2-dimethyl-cis-(and-trans-)-3-vinylcyclopropyl] cuprates were prepared in a highly stereoselective fashion and were allowed to react with 3-iodo-2- cyclohexen-1-one and 3-iodo-2-methyl-2-cyclo-hexen-1-one. The Cope rearrangement of the resultant products [~-(2, 2-dimethyl-3-vinylcyclopropyl) cyclohex-enones] was investigated.
