Abstract | The Ti(IV)-catalyzed Ugi condensation of alpha-amino acids with electron-rich aromatic aldehydes performs adequately even with sterically demanding alpha-amino carboxylate salts. The reaction occurs diastereoselectively, in some cases with virtually complete diastereoselectivity. A stereochemical rationale for the reaction is proposed. |
