✦ Synopsis

reoeived in UK for publication 4 Maroh 1974) Conjugated cyclopentenones (III) substituted at 2-and 3-positions involve such important compounds as jasmone and prostaglandin B family, 1 and also intermediates for synthesizing muscone' or [nlmetacyclophanes. 3 This communication discloses a new route to III from cross-conjugated, symmetrical dienones (I) or their ethylene acetals (II).
