The first examples are presented of double Diels-Alder cycloadditions used, as dienophiles, 2(1H)-pyridones, and of Diels-Alder cycloaddition of 1-unsubstituted 2(1H)-pyridone acting as a dienophile under atmospheric and high pressure conditions.
本文首次举例说明了以 2(1H)-
吡啶酮为亲二烯体的双 Diels-Alder 环加成反应,以及在常压和高压条件下以 1-未取代的 2(1H)-
吡啶酮为亲二烯体的 Diels-Alder 环加成反应。
