We report the short synthesis of two natural products, rosmaridiphenol and taxamairin B, from key intermediates 5a and 5b, which were prepared from enynals 8a and 9b, respectively, by using a gold-catalyzed cyclization reaction. This approach can be widely applied in the synthesis of [6,7,6]-fused tricyclic compounds found in many icetexane diterpenoids.
我们报告了通过使用金催化的环化反应,分别从烯类8a和9b制备的关键中间体5a和5b简短合成了两种天然产物rosmaridiphenol和taxamairinB 。该方法可广泛应用于许多冰ice烷二萜类化合物中[6,7,6]稠合的三环化合物的合成中。
