Synthesis of a Library of Imidazolin-4-ones Using Poly(ethylene glycol) as Soluble Support.

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