title: A simple and convenient method for acyclonucleoside synthesis.
abstract: Introduction of acyclic chain for synthesis of acyclonucleoside derivatives was achieved in a simple and convenient way. Silylated pyrimidine or purine bases were treated with 1,3-dioxolane, trimethyl chlorosilane and metal iodide, such as KI and NaI, all together at room temperature. By this method, 2-thiopyrimidine derivatives were also obtained in good yield, using 2 molecular equivalents of 1,3-dioxolane.
