Application

An Efficient Additive for Condensation Reactions

Experimental procedure: to a solution of 1 (1 mmol) in anhydrous DMF (10 mL) is added N-Hydroxy-5-norbornene-2,3-dicarboximide (1.1 mmol) and DIC (1.1 mmol) in one portion. Reaction mixture is stirred for additional 5 min at 0 °C and then L-ProNH2(2, 1 mmol) is added. The reaction is stirred for additional 36 h at 4 °C. Solvent is evaporated under reduced pressure and the crude product is purified by column chromatography using MeOH/CH2Cl2 (15:85) as eluant to afford 3 as a white solid in 77% yield.
