Carbonylative negishi-type coupling of 2-Iodoglycals with alkyl and aryl halides
C-Glycosides are valuable organic compounds in the field of medicinal chemistry due to their ubiquity inside living systems and pronounced biological activity. Herein, we describe an approach to alkyl-ketones bearing glycal units via the Pd-catalyzed carbonylative coupling of 2-iodoglycals and alkyl and aryl halides. Examples bearing a variety of functional groups are presented as well as a mechanistic proposal for this transformation.
