by the electron-donating properties of the starting heterocycle. The generated imidazo[1,2]hetarylglyoxylates undergo standard transformations typical of α-keto esters upon reaction with various nucleophiles. All the products contain an imidazoheterocyclic scaffold which is considered a privileged structure for drug discovery. imidazoheterocycles - acylation - glyoxylates - privileged scaffolds
据报道,一种实用的方法是通过母体稠合的咪唑与乙二酰氯的Friedel-Crafts酰化反应来制备咪唑并[1,2]杂芳基乙醛酸酯。该反应受起始杂环的电子给体性质强烈影响。与各种亲核试剂反应后,生成的咪唑并[1,2]杂芳基乙醛酸酯会经历典型的α-酮酯标准转化。所有产品均包含咪唑杂环骨架,该骨架被认为是药物发现的优先结构。 咪唑杂环-酰化-乙醛酸酯-特权支架
