A cat of all trades: A single copper catalyst promoted up to three reaction steps with separate catalytic cycles in a domino sequence (azide–alkyne cycloaddition/Goldberg amidation/Camps cyclization/(CH arylation)) for the rapid construction of complex heterocycles from three simple components under mild conditions (see scheme). Facile cleavage of the triazole ring enables further elaboration of the
无所不包的行业:单个铜催化剂可促进多达三个反应步骤,并在多米诺序列中具有独立的催化循环(叠氮化物-炔烃环加成反应/金伯格酰胺化/校园环化/(CH芳基化)),可快速构建复杂的杂环在温和条件下由三个简单成分组成(请参阅方案)。三唑环的容易裂解使得能够进一步精制缩合产物。
