title: Use of Conjugated Dienones in Cyclialkylations: The Total Syntheses of (+/-)-Barbatusol, (+/-)-Pisiferin, (+/-)-Deoxofaveline, (+/-)-Xochitlolone, and (+/-)-Faveline.
abstract: Concise syntheses of five tricyclic diterpenoids are reported. The key reaction in each synthesis is a cyclialkylation of a functionalized arene with a Lewis acid-activated conjugated dienone to generate a 6,7,6-fused tricycle.
