Merging radical catalysis and noncovalent stereocontrol concepts toforge native O-glycosidic linkages
《Science Bulletin》2024年第21期3308-3310,共3页Hao Guo Charles C.J.Loh 
Stereoselective carbohydrate synthesis[1,2]has experiencedimmense strides in the last few years,benefiting from assimilatingknowledge at the frontiers of modern synthetic concepts.On thisfront,the dual but parallel dev...
