title: Convergent formal syntheses of (+/-)-brussonol and (+/-)-abrotanone via an intramolecular Marson-type cyclization.
abstract: The formal convergent syntheses of both (+/-)-brussonol and (+/-)-abrotanone are reported. The key step involved the diastereoselective capture of an in situ generated oxocarbenium cation via an intramolecular Friedel-Crafts/Marson-type cyclization.
