Glutamine dehydration

The carboxamide groups of asparagine and glutamine derivatives 26 are susceptible to dehydration during carbodiimide-mediated esterification at the a-carboxy groups (Scheme 4).[64] reaction probably involves formation of aspartyl- or glutamylisoimide 28 by attack... [Pg.447]

Addition of trapping agents such as N-Hydroxysuccinimide and 1-Hydroxybenzotriazole (HOBt) reduce the extent of many side reactions, especially Al-acylurea formation. Also, racemiza-tion is suppressed when these additives are present. The latter reagent eliminates the intramolecular dehydration of < >-amides of asparagine and glutamine that occurs with carhodiimides (eq 2). - ... [Pg.184]
