unexpectedly, after elimination of the sulfoxide, the naphthol (10). The successful route to cannithrene 1 (1) involved regiospecific demethylation of 6,8-dimethoxytetralone, then its conversion to enone 16. Pyridinium bromide perbromide provided the necessary aromatization to give cannithrene 1 (1) after deprotection by hydrogenolysis. The 13C nmr assignments of 1 were made.
已经探索了两种合成大麻烯 1 (1) 的方法。6,8-二甲氧基四氢萘酮的一锅退火首先形成β-酮亚砜,然后加入甲基乙烯基酮,出人意料地在消除亚砜后得到萘酚(10)。获得 Cannithrene 1 (1) 的成功途径涉及 6,8-二甲氧基四氢萘酮的区域特异性去甲基化,然后将其转化为烯酮 16。溴化吡啶提供必要的芳构化,在氢解脱保护后得到 Cannithrene 1 (1)。进行了 1 的 13C nmr 分配。
