Transient imine as a directing group for the Pd-catalyzed anomeric C(sp 3 )–H arylation of 3-aminosugars
Résumé
The first example of Pd( ii )-catalyzed anomeric C(sp 3 )–H arylation of 3-aminosugars by using a transient directing group approach is reported. The free amine was then exploited in a CuAAC reaction to access to a variety of C3-triazolo C -glycosides in good yields.
