The Diels-Alder reaction of anthrone or 3-hydroxy-2-pyrone and methyl 4-hydroxy-2-butenoate proceeds efficiently by the use of phenylboronic acid as a template, giving the cycloadducts with high regio- and stereoselectivity.
以苯硼酸为模板,蒽酮或 3-羟基-2-吡喃酮与 4-羟基-2-丁烯酸甲酯的 Diels-Alder 反应可以高效地进行,生成的环加合物具有很高的区域和立体选择性。
