text] A variety of biologically interesting dihydrofurocoumarins have been synthesized in high yields by the palladium-catalyzed annulation of 1,3-dienes by o-iodoacetoxycoumarins. This reaction is very general and regioselective, and a wide variety of terminal, cyclic, and internal 1,3-dienes can be utilized.
[反应:见正文]通过邻碘乙酰乙酰氧基香豆素经钯催化的1,3-二烯环化反应,已高收率合成了多种生物学上有趣的二氢呋喃香豆素。该反应是非常普遍的和区域选择性的,并且可以使用各种各样的末端,环状和内部的1,3-二烯。
