专利号:US-12098126-B2 优先权日:2021-08-23 标题:Methods of iron catalyzed C-H bond amination 发明人:CHE CHI-MING; YOU TINGJIE 权利人:VERSITECH LTD; LABORATORY FOR SYNTHETIC CHEMISTRY AND CHEMICAL BIOLOGY LTD 摘要:Described herein is an iron(II)-phthalocyanine catalyzed C—H bond amination of alkyl azides. The catalyst is effective to produce intramolecular amination of saturated C—H bonds in moderate to excellent yields and the methods are tolerant of a wide scope of substrates. The methods described are useful for the synthesis of natural products derivatives and for the late-stage functionalization of pharmaceuticals.
