A catalytic and highly efficient Wolff's cyclocondensation of α-diazoketones with aromatic and aliphatic amines has been realized for the first time by utilizing the strategy of an intramolecular hydrogen bonding-activating carbonyl group. This approach successfully solved the challenging problem of poor condensation efficiency in Wolff 1,2,3-triazole synthesis, and constitutes a powerful method for the synthesis of highly functionalized 1,2,3-triazoles.
通过利用分子内氢键活化羰基的策略,实现了催化高效Wolff酮内α-重氮酮与芳香胺和脂肪胺的环化缩合反应,成功解决了Wolff型1,2,3-三氮唑合成中缩合效率低下的难题,成为合成高度功能化1,2,3-三氮唑的有力方法。
