The syntheses of several 3-(1,1-dimethylallyl)coumarins, simple or bearing additional furan or pyran rings is achieved starting from the corresponding C-3 unsubstituted derivatives. The key step involves Ireland-Claisen rearrangements of allyl esters.
从相应的C-3未取代的衍生物开始,可以实现几个简单的或带有额外的呋喃或吡喃环的几种3-(1,1-二甲基烯丙基)香豆素的合成。关键步骤涉及烯丙酯的爱尔兰-克莱森重排。
