A concise, convergent synthesis of (±)-frondosin B has been developed based on the application of a StilleâHeck reaction sequence of 2-chloro-5-methoxybenzo[b]furan-3-yl triflate and 2-(3-butenyl)-3-(trimethylstannyl)cyclohex-2-enone giving the racemic natural product in a 34% overall yield.
基于 2-氯-5-甲氧基苯并[b]呋喃-3-基三氯酸盐和 2-(3-丁烯基)-3-(三甲基锡基)环己-2-烯酮的 StilleâHeck 反应序列,我们开发出了一种简便的 (±)-frondosin B 趋同合成方法,并以 34% 的总收率得到了外消旋天然产物。
