gem-Difluoro-1,7-enyne amides are suitable building blocks for the synthesis of difluorodihydropyridinones via a ring-closing metathesis reaction, and of 4,4-difluoro-3-oxoisoquinolines through a ring-closing metathesis–enyne metathesis tandem reaction. These products, in turn, undergo a Diels–Alder reaction to yield heterotricyclic systems in moderate to good yields.
-Difluoro-1,7-烯胺是通过环闭合重要反应合成二氟二氢吡啶酮的适用构建块,以及通过环闭合烯烃重要反应合成4,4-二氟-3-氧代异喹啉的适用构建块。这些产物反过来通过Diels–Alder反应形成中等至良好的产率的杂三环系统。
