Microwave-assisted treatment of various heterocyclic amides (benzodiazepinone, phthalazone) with TiCl4 in the presence of primary or secondary amines provides the corresponding amidines. In addition to the interest of the microwaves for this reaction, our study highlights the higher reactivity of the cyclic acetamide moiety compared to the cyclic benzamide moiety towards this TiCl4-mediated reaction.
在伯胺或仲胺存在下,用 TiCl4 对各种杂环酰胺(苯并二氮杂庚酮、酞嗪酮)进行微波辅助处理,可以得到相应的酰胺。除了微波对这一反应的作用外,我们的研究还突出表明,与环状苯甲酰胺相比,环状乙酰胺对这种 TiCl4 介导的反应具有更高的反应活性。
