Monoacetals of ο,ο'-dialdehydes 3 are converted (Z)-stereospecifically into (Z)-unsaturated ο-acetal-carboxylic-acids 5 and 12, respectively.Replacement of the hydroxylic group by the ylid function, followed by acetal cleavage and an intramolecular (E)-stereospecific Wittig reaction yields (E,Z)-cyclodienones 10 and 14, respectively.Subsequent reduction of 14 affords civetone 15.
