oxygen has been developed. Both activated and unactivated free amines were oxygenated efficiently to provide a wide variety of amides (primary, secondary) and lactams under operationally simple conditions without the aid of metallic reagents and toxic oxidants. The method has been applied to the synthesis of highly functionalized amide-containing medicinal drugs, such as O-Me-alibendol and -buclosamide
α-CH的直接氧化2组的游离胺难以实现由于胺部分的较高的反应性。因此,胺的氧化涉及在敏感反应条件下在存在或不存在危险氧化剂的情况下使用复杂的金属试剂/催化剂。已经开发了一种通过无氧活化分子氧直接对脂肪族胺进行CH–H氧化的新方法。在操作简单的条件下,无需金属试剂和有毒氧化剂的帮助,可以将活化的和未活化的游离胺都有效地氧化,以提供多种酰胺(伯,仲)和内酰胺。该方法已用于合成高度官能化的含酰胺药物,例如O-Me-阿里苯多和-buclosamide。
