  摘要：

  2-烷基-4,5-二氢咪唑与α,β-不饱和醛和酮通过N-1氮原子的共轭加成和随后的亚胺-醛醇缩合反应发生环化，形成具有与带有C(α)活化基团的二氢咪唑不同的环化反应区域选择性的咪唑[1,2-a]吡啶；与β-酮酸酯的环化也能得到咪唑[1,2-a]吡啶，但此时的区域选择性与C(α)活化的二氢咪唑一致， necessitating对早期报告的结构进行修正。双烷基乙炔二羧酸酯经历共轭N-加成，但作为1,2-而非1,3-双电离体，形成吡咯[1,2-a]咪唑。

  imidazolines were reacted with an acyl-Meldrum's acid derivative under acidic conditions. To prepare the oxygen analogs, a one-pot procedure was developed that allowed synthesis of dihydrooxazolo ring-fused 2-pyridones starting from acylated serine derivatives. After hydrolysis to their corresponding carboxylic acids and lithium carboxylates, biological evaluation revealed that the sulfur could be replaced

  先前已证明二氢噻唑环稠合的2-吡啶酮可抑制尿路致病性大肠杆菌中的菌毛组装。现在已经开发出合成二氢咪唑啉和二氢恶唑环稠合的2-吡啶酮的方法。为了获得氮类似物，使Cbz保护的咪唑啉在酸性条件下与酰基-梅德鲁姆酸衍生物反应。为了制备氧类似物，开发了一种一锅法，该程序允许从酰化的丝氨酸衍生物开始合成二氢恶唑啉环稠合的2-吡啶酮。水解成相应的羧酸和羧酸锂后，生物学评估表明硫可以被氧原子取代，并且仍然保持抑制尿路致病性大肠杆菌中菌毛组装的能力。。然而，引入仲胺而不是氧气导致生物活性大大降低。
