H. Taguchi et al., UNEXPECTED REACTION OF DIPEPTIDYL CHLOROMETHYL KETONE DURING ACID-HYDROLYSIS, Journal of the Chemical Society, Chemical Communications, (3), 1994, pp. 247-247
Amino acid recovery of dipeptidyl chloromethyl ketones is remarkably l
ow owing to the formation of 2-hydroxy-3,6-dialkyl-5-methylpyrazine du
ring acid hydrolysis.
