N-carboxy-gamma-methyl-L-glutamic anhydride → HCID 89839269, compound

Participants

Reaction Steps

N-carboxy-L-alanine anhydride and N-carboxy-γ-methyl-L-glutamic acid anhydride were added to benzene at a molar ratio of 9:1, total 1.4 wt %, and the mixture was stirred for 2-3 days to give a poly-L-alanine/γ-methyl-L-glutamic acid copolymer (9/1). This was dissolved in a dichloromethane-trifluoroacetic acid mixed solvent (50:50 (v/v)) to give a 8 wt % poly-L-alanine/γ-methyl-L-glutamic acid copolymer (9/1) solution. A fiber structure made of poly-L-alanine/γ-methyl-L-glutamic acid copolymer (9/1) was obtained from this solution in the same manner as in Production Example 1.
