N-(N-Formyl-L-alpha-aspartyl)-3-phenyl-L-alanine → N-formyl-L-beta-aspartyl-L-phenylalanine

Participants

Reaction Steps

Thereafter, the N-formyl-L-α-aspartyl-L-phenylalanine (hereinafter simply referred to as For-α-AP) in the reaction mixture was quantitatively analyzed by HPLC (High performance Liquid Chromatography), to find that it had been formed in a Yield of 68.2% based on the L-phenylalanine sodium salt monohydrate. In addition, 30.0% of N-formyl-L-β-aspartyl-L-phenylalanine (For-β-AP), etc. had been by-produced.
