developed a novel rhodium(I)-catalyzed cascade reaction involving the hydroacylation of a 4,6-dienal followed by cycloisomerization of the resulting 1,3-diene with an alkene, giving carbocycles containing a bicyclo[5.3.0]decenone skeleton in a stereoselective manner. Herein, we report the construction of the C5,C7,C6-tricyclic core of guanacastepenes using this cascade reaction. rhodium - cascade reactions
我们先前开发了一种新型的铑(I)催化的级联反应,涉及4,6-二烯的加氢酰化,然后将生成的1,3-二烯与烯烃进行环异构化,从而得到含有双环[5.3.0]癸烯酮骨架的碳环以立体选择的方式。在本文中,我们报道了使用该级联反应构建胍卡斯汀的C 5,C 7,C 6-三环核。 铑-级联反应-二烯-醛-胍卡斯汀
