The invention provides a catalytic, chemospecific and stereospecific method of oxidizing a wide variety of substrates without unwanted side reactions. Essentially, the method of the instant invention, under relatively mild reaction conditions, catalytically, stereospecifically and chemospecifically inserts oxygen into a hydrocarbon C—H bond. Oxidation (oxygen insertion) at a tertiary C—H bond to form an alcohol (and in some cases a hemiacetal) at the tertiary carbon is favored. The stereochemistry of an oxidized tertiary carbon is preserved. Ketones are formed by oxidizing a secondary C—H bond and ring-cleaved diones are formed by oxidizing cis tertiary CH bonds.
该发明提供了一种催化、化学特异性和立体特异性的氧化方法,可以在没有不必要的副反应的情况下氧化各种底物。本发明的方法在相对温和的反应条件下,在烃的C—H键中催化、立体特异性地和化学特异性地插入氧。对于三级C—H键的氧化(氧插入),形成醇(在某些情况下还有半缩醛)在三级碳上更有利。氧化次级C—H键形成酮,氧化顺式三级CH键形成环裂二酮。
