A number of 2-azetidinones were synthesized in good to excellent yields by a novel reaction between Schiff bases, substituted acetic acids and alkoxymethylene-N,N-dimethyliminium salts, the adduct formed from DMF and O-alkylating agents. The advantages of this new method are mild reaction conditions

A modified poly(ethylene glycol) (PEG) has been developed for the soluble-polymer-supported synthesis of b-lactams. The monomethylether of PEG (MeOPEG) with an average M W of 5000 was used as the support, a 4-(3propyl)phenyl residue as the spacer, and a 4-oxyphenylamino group as the moiety with the

A new polymer-supported TBTU (P-TBTU) has been prepared from polystyrene-bound 1-hydroxybenzotriazole (P-HOBT) and used efficiently as a solid-supported reagent for peptide-coupling reactions, and is even effective with wet solvents. The P-HOBT can be recovered by simple filtration and reused for th
