Abstract

Abstract1,4-Conjugate addition of arylboronic acids to the glycal enones delivered 2-deoxy-α-aryl-C-glycosides in good yields. The reaction was catalyzed by palladium acetate in the presence of trifluoroacetic acid and 1,10-phenanthroline. A wide range of glycal enones derived from d-glucal, d-galactal, and d-rhamnal participated in the coupling reaction with different arylboronic acids smoothly. Different protecting groups including benzyl, acetyl, pivaloyl, and benzoyl were compatible under optimized conditions.
