Provided are cyclopropanecarboxamido-substituted aromatic compounds that inhibit protein kinases and their use in anti-tumor area. In particular, tyrosine-kinase inhibitors and Raf-kinase inhibitors as anti-tumor agents, their preparation, pharmaceutical composition, and their use in the treatment of cancer are also provided.
By using cheap and innocuous sodiumchlorite, a series of tertiary amines have been oxidized to the corresponding lactams with good selectivity and high yield. In this method, neither transition-metal catalyst nor oxidant was used. In the oxidation step, the pH of the sodiumchlorite was precisely adjusted to pH around 6 using CO2, such pH is a compromise between oxidative properties, chemical stability
通过使用廉价、无害的亚氯酸钠,一系列叔胺被氧化成相应的内酰胺,具有良好的选择性和高收率。在该方法中,既不使用过渡金属催化剂,也不使用氧化剂。在氧化步骤中,使用 CO 2将亚氯酸钠的 pH 值精确调节到 6 左右,这样的 pH 值是氧化特性、化学稳定性和不需要的沉淀之间的折衷。此外,缓冲盐不是必需的,这使得这种氧化反应可以在安全和环境友好的条件下进行。
