Several representative 3,4,8-trisubstituted 1,4-diazabicyclo[3.4.0]nonan-2-ones have been prepared employing solid phase methodologies. Elaboration of a 4-hydroxyproline derivative with an 15N-amino acid derivative allowed convenient monitoring of the reaction sequence on solid support by gel-phase 15N NMR. An intramolecular Mitsunobu cyclization provided the desired heterocycle, which could be further functionalized at the 4-position. This synthetic method is facile, general, and suitable for the construction of large libraries of compounds for biological assays.
