在室温条件下, 2-三氯乙酰基吡咯经溴代反应, 再与氨基酸甲酯反应得到一系列N-(溴代-2-吡咯甲酰基)氨基酸甲酯, 收率为64.8%～92.2%. 通过元素分析, 1H NMR, IR和MS对产物结构进行了表征, 培养了N-(1-甲基-4,5-二溴-2-吡咯甲酰基)甘氨酸甲酯的单晶并进行单晶X射线衍射分析. 初步活性试验表明, 目标产物对金黄色葡萄球菌、粪链球菌等五种细菌有一定的抑制作用.

A series of N-(methoxycarbonylalkyl)bromopyrrole-2-carboamides were synthesized by acylation of amino acid methyl esters with bromo-2-trichloroacetylpyrroles at room temperature in 64.8%～92.2% yields. The structures of products were determined on the basis of 1H NMR, IR, MS spectra and elemental analyses. One of these products was analyzed by single crystal X-ray diffraction. Preliminary antibiotic tests showed that some target compounds inhibit the five bacteria such as Staphylococcus aureus and Streptococcus faecalis.

Key words: bromization, synthesis, antibiotic activity, acylation, N-(methoxycarbonylalkyl)bromopyrrole-2-carboamide
