Synthesis of 5-alkynylated uracil–morpholino monomers using Sonogashira coupling
摘要:
Sonogashira coupling of 5-iodo uracil-morpholino monomer with different terminal alkynes has been achieved for first time in good to excellent yields (67-86%). We have optimized the iodination conditions for the preparation of 5-iodo uracil-morpholino monomer under basic condition. (C) 2012 Elsevier Ltd. All rights reserved.
