title: Convenient synthesis of functionalized bis-ureidopyrimidinones based on thiol-yne reaction.
abstract: The preparation of functionalized bis-ureidopyrimidinones (Bis-UPy) through the thiol-yne reaction is described. Various Bis-UPys with different functional groups were synthesized by using the readily available functionalized alkynes and UPy-thiol to affirm the simplicity and versatility of the methodology.
