A hetero Diels-Alder reaction with inverse electron demand between 4-hydroxycoumarin, aromatic aldehydes and electron-rich alkenes yielded a multitude of 2,4-disubstituted 3,4-dihydropyranocoumarins. This route opened an easy access to coumarin anticoagulants and provided a library of pyranocoumarin derivatives.
在4-羟基香豆素,芳族醛和富电子烯烃之间进行反电子需求的杂Diels-Alder反应产生了大量的2,4-二取代的3,4-二氢吡喃香豆素。这条路线为香豆素抗凝剂的开发提供了方便,并提供了吡喃香豆素衍生物库。
