The Facile Solid-Phase Synthesis of Thiazolo-Pyrimidinone Derivatives

A thiazolo-pyrimidinone derivative library was developed through a facile solid-phase synthesis method. For the reaction, the thiazolo[4,5- ]pyrimidin-7(6 )-one structure was synthesized through efficient Thorpe-Ziegler and cyclization reactions. The thiazolo[4,5- ]pyrimidin-7(6 )-one derivative library with a diversity of three had a total of four synthesis steps and 57 compounds. In addition, the yield per synthesis step was 65-97%, which was very high. The developed synthesis method and compounds will be used to find compounds with biological activity through the thiazole derivative structure-activity relationship.
