Abstract
Abstract 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.
