Use of Conjugated Dienones in Cyclialkylations: The Total Syntheses of (±)-Barbatusol, (±)-Pisiferin, (±)-Deoxofaveline, (±)-Xochitlolone, and (±)-Faveline
摘要:
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.

Simple and efficient syntheses of the cytotoxic benzocycloheptenes (±)-deoxofaveline(1) and (±)-faveline methyl ether(2) have been developed by a convergent route from the ketone 7 via the tricyclic ketone12.

An efficient, flexible, and stereoselective convergent route for constructing the trans-10-hydroxy-1,1-dimethyloctahydrodibenzo[a,d]cyclohepten-7-ones (5a−c) was achieved via intramolecular Heck reaction. This strategy has been successfully implemented for the syntheses of (±)-komaroviquinone (3) through (±)-coulterone dimethyl ether (5c) and (±)-faveline methyl ether (1a).
