Two new synthetic routes for (E)-N-methyl-2-styryl-4-quinolones have been established, both starting from (E)-2′-cinnamoylaminoacetophenones. In the first, (E)-2′-cinnamoylaminoacetophenones are cyclized and then methylated, while in the second they are methylated followed by in situ cyclization.
已经建立了两条新的(E)-N-甲基-2-苯乙烯基-4-喹啉酮合成路线,均以(E)-2′-肉桂酰氨基苯乙酮为起点。在第一种方法中,(E)-2′-肉桂酰氨基苯乙酮先环化再甲基化,而在第二种方法中,它们先甲基化再原位环化。
