developed a simple and efficient protocol to aminomethylate the C‐3 position of imidazo[1,2‐a]pyridine through a multicomponent, decarboxylation reaction involving imidazo[1,2‐a]pyridine, a secondary amine, and glyoxylic acid. The developed protocol requires mild reaction conditions and furnishes diverse imidazo[1,2‐a]pyridine analogues from commercially available starting materials.
我们开发了一种简单而有效的协议来aminomethylate咪唑并[1,2的C-3位一个通过多组分]吡啶,脱羧反应涉及咪唑并[1,2一]吡啶,仲胺,和二羟乙酸。制定的方案要求反应条件温和,并从市售起始原料中提供多种咪唑并[1,2- a ]吡啶类似物。
