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).
通过分子内Heck反应实现了构建反式-10-羟基-1,1-二甲基八氢二苯并[ a,d ]环庚-7-酮(5a - c)的有效,灵活和立体选择性的聚合途径。该策略已成功实施,用于通过(±)-香豆酮二甲醚(5c)和(±)-faveline甲醚(1a)合成(±)-科马罗维醌(3)。
