Polysubstituted 5-functionalized 2-pyrone derivatives were synthesized via the K 2 CO 3 -catalyzed reaction of 1,2-allenyl esters and α-substituted ketones with electron-withdrawing groups through a tandem nucleophilic addition/lactonization process.
多取代的5-官能化2-吡喃酮衍生物是通过1,2-烯基酯和α-取代酮与吸电子基团通过串联亲核加成/内酯化过程的K 2 CO 3 催化反应合成的。
