An effective synthesis of 2,3-disubstituted 2-cyclopentenones involves C4 - C3 ring contraction of the readily available 1,2-disiloxycyclobutene followed by thermal C3 - C5 ring enlargement of trimethylsiloxyvinyl-cyclopropanes.To illustrate the convenience of this new approach the total syntheses of 2-methyl-3-p-tolyl-2-cyclopentenone, dihydrojasmone, and cis-jasmone are reported.
