【摘要】采用改进的Hantzsch反应,在氮气保护下的封闭体系中回流芳香醛、乙酰乙酸乙酯和NH4HCO3,合成了1,4-二氢吡啶衍生物(1a~1d),其结构经1HNMR,IR和元素分析确认。用XRD测定了1b的晶体结构。更多还原

【Abstract】 1,4-Dihydropyridine derivatives(1a~1d) were synthesized by improved Hantzsch reaction of aromatic aldehyde, ethyl acetoacetate and NH4HCO3 in a closed system filled with nitrogen gas under refluxing. The structures were confirmed by 1H NMR, IR and elemental analysis. The crystal structure of 1b was determined by XRD.更多还原
