chlorides and N-heterocycles activated in situ with ethyl chloroformate has been accomplished at room temperature using copper iodide as catalyst. This economical and practical carbon–carbon bond formation provides convenient access to a variety of 3-aminoynones from aliphatic and aromatic acyl chlorides in up to 99% yield. The addition to pyridines and quinolines occurs under almost identical conditions and
使用碘化铜作为催化剂,在室温下将炔酰胺添加到酰氯和用氯甲酸乙酯原位活化的N-杂环中。这种经济实用的碳-碳键形成可以方便地从脂肪族和芳香族酰氯中以高达 99% 的产率获得各种 3-氨基炔酮。吡啶和喹啉的添加发生在几乎相同的条件下,并以良好到高的区域选择性进行,以高达 95% 的产率生成相应的 1,2-二氢-N-杂环。
