catalysis of CuI/1H-pyrrole-2-carboxylic acid. The coupling products underwent oxidation to afford the azo compounds, which were subjected to deprotection with TFA and in situ cyclization to give 1,2,4-benzotriazines.
在CuI/1H-吡咯-2-羧酸的催化下,邻卤代乙酰苯胺和N-Boc肼的偶联在室温下进行。偶联产物经过氧化得到偶氮化合物,然后用三氟乙酸脱保护并原位环化得到 1,2,4-苯并三嗪。
