been conveniently applied as carbon-carbon bond forming reaction for the assemblage of the functionalized carbon atom fragments required for the synthesis of two simple but different targets such as the macrolide antibiotic (−)-pyrenophorin 1 and rosefuran 2, a trace component of the high prized oil of rose. In both cases, an intermediate 3,5-disustituted isoxazoline ring system has been used as serviceable
