                                    The palladium-catalyzed reaction of 6-tributylstannyluridine derivative 5 with a variety of aryl, vinyl, alkynyl, and allyl halides provides an efficient method for the synthesis of the corresponding cross-coupled products. In all cases, an enhancement on the rate and isolated yields was attained by using Cul as co-catalyst.
