A library of imidazolin-4-ones has been synthesized using poly(ethylene glycol) (PEG) as soluble polymer support. The imidazolin-4-ones 6 or 7 were synthesized effectively by reaction of primary amine with PEG-supported carbodiimides 4, which were obtained from aza-Wittig reaction of PEG-supported iminophosphoranes 3 with isocya...
