heterocyclyl ethylation

Methods By the reaction of acetyl heteroarylcycles such as acetyl pyridiness,acetyl thiophenes,or acetyl furans and the like,with N,N-dimethylformamide dimethylacetal in xylene solvent at 140℃ for 24 hours,3-dimethylamino-1-heteroaryl-2-propen-1-ones were prepared.

方法用二甲苯作为溶剂,使N,N-二甲基甲酰胺二甲基缩醛与乙酰基芳杂环类化合物,如乙酰吡啶、乙酰噻吩和乙酰呋喃等,在138℃反应24 h,生成3-N,N-二甲基氨基-1-芳杂环基-2-丙烯-1-酮类化合物,并对目标化合物进行了分析鉴定及表征。
