A novel analog of nucleic acids bearing an optically active serine ester backbone, serine-based nucleobase-linked polyester (SNE), was synthesized. Monomers containing a thymine base were synthesized from L- and D-serines. Furthermore, reaction conditions were thoroughly examined for the ester bond formation by using a new phosphonium-type condensing reagent oil a solid support without racemization. The release of the dimer from the resin was also investigated using a new type of linker, which could be cleaved under neutral conditions. (c) 2006 Elsevier Ltd. All rights reserved.
