Both enantiomers of 13-pentadecanolide and 15-heptadecanolide, higher analo
gues of galbanum macrolides, were prepared via ring enlargement of cyclodec
anone and cyclododecanone, respectively. Conversion of the intermediate oxo
lactones to methylenated ethyl galbanum macrolides by Wittig olefination s
hifted the olfactory properties dramatically. (C) 1999 Elsevier Science Ltd
