A [4 + 2] annulation involving cascade Knoevenagel, aza-Wittig and dehydrofluorination reactions is developed for the synthesis of substituted quinolin-4-ols including analogs bearing CF2H, CF3, and C2F5 groups. This simple and highly efficient method is also applicable for the synthesis of substituted quinolines. A number of reported biologically active compounds can be readily prepared by this one-pot
开发了一种包括级联Knoevenagel,aza-Wittig和脱氟化氢反应的[4 + 2]环合反应,用于合成取代的喹啉-4-醇,包括带有CF 2 H,CF 3和C 2 F 5基团的类似物。这种简单而高效的方法也适用于取代喹啉的合成。通过一锅法合成可以容易地制备许多报道的生物活性化合物。新反应过程的绿色化学指标分析提供了令人满意的结果。
