ylic acid, and terminal alkynes was developed under very mildconditions. This method allows the introduction in one pot of a third ring fused in positions 2 and 3 of the imidazo[1,2-a]pyridine core with reasonable yields and total regioselectivity. This procedure does not require the use of any expensive supplementary additives, and is palladium-free.
一般有效的Cu(I)介导的C的交叉偶联和杂环化反应3-碘咪唑并[1,2- a ]吡啶-2-羧酸,并且末端炔烃是在非常温和的条件下形成的。该方法允许以合理的收率和总区域选择性在一个锅中引入稠合在咪唑并[1,2- a ]吡啶核的2和3位的第三环。该步骤不需要使用任何昂贵的补充添加剂,并且不含钯。
