An efficient one-pot method for the synthesis of functionalized quinolines and tetrahydronaphthyridines has been developed. The photo-Fries rearrangement of p-substituted anilides afforded differently substituted o-amino ketones that reacted in situ with acetylenic Michael acceptors such as dimethyl acetylenedicarboxylate (DMAD) to give 6,4-disubstituted quinoline 2,3-dicarboxylates. Starting from anilides
已经开发了一种用于合成官能化喹啉和四氢萘吡啶的有效的一锅法。对位取代的苯胺的光-弗里斯重排得到不同取代的邻氨基酮,其与炔属迈克尔受体如乙炔基二羧酸二甲酯(DMAD)原位反应,得到6,4-二取代的喹啉2,3-二羧酸酯。从衍生自β-丙氨酸的苯胺开始,也可以组装萘啶核。
