Regioselective Allylations of Pyrimidine Ribonucleosides Using Pd(0) Catalyst

Kumar, Vaijayanti,Gopalakrishnan, Vidhya,Ganesh, K. Nagappa

, p. 1665 - 1667 (2007/10/02)

A novel procedure for regiospecific O-allylation of pyrimidine ribonucleosides is reported by using Pd(PPh3)4-allyl ethyl carbonate reagent to synthesize 2'-O-allyluridine and 2'-O-allylcytidine. 3-N-allylation of the pyrimidine ring is prevented by prote
