)-ones with nitriles, followed by N-acetylation of the resulting vinylogous urea derivatives with acetic anhydride/pyridine and double bond migration with l,8-diazabicyclo[5.3.0]undec-7-ene, affords 3-[l-(acetylamino)alkyl]-l-methylquinolin-2(1H)-one derivatives in reasonable overall yields.
用腈处理 1-methyl-3,4-dihydroquinolin-2(1H)-ones 的烯醇镁化物,然后用乙酸酐/吡啶对所得的乙烯基脲衍生物进行 N-乙酰化,并用 1,8-二氮杂双环进行双键迁移[5.3.0]undec-7-ene 以合理的总产率提供 3-[1-(乙酰氨基)烷基]-1-甲基喹啉-2(1H)-one 衍生物。
