| | N-Ethoxycarbonyl-2-ethoxy-1,2-dihydroquinoline Usage And Synthesis |
| Chemical Properties | White to pale yellow solid | | Uses | Peptide condensing agent with little or no racemization. Amidation coupling reagent. | | Uses | In the synthesis of peptides. | | Uses | 2-Ethoxy-1-ethoxycarbonyl-1,2-dihydroquinoline is an irreversible membrane-bound receptor antagonist. It is used in synthetic chemistry, discovery, process R&D. It also acts as coupling reagents. | | Purification Methods | Dissolve EEDQ ~180g in CHCl3, evaporate to dryness in a vacuum. Add dry Et2O (20mL) and a white solid separates on standing. Set aside for a few hours, collect the solid, wash it thoroughly with cold Et2O and dry it in a vacuum (~140g, m 63.5-65o). A further crop of solid (~25g) is obtained from the filtrate on standing overnight. [Fieser & Fieser Reagents for Organic Synthesis 2 191 1969, Belleau et al.
