straightforward solid-phase synthesis of 2-aminoimidazolone derivatives is described. The synthesis starts with immobilization of thioureas onto solid support, followed by HBTU/DIEA assisted coupling of Boc-protected aminoacids. Upon removal of the Boc group, intramolecularcyclization and simultaneous cleavage are promoted by polyamine resin to give the 2-aminoimidazolone derivatives in good yields and excellent
