Application

L-Pyroglutamic acid is used in the synthesis of:
  • Nonproteinogenic amino acids such as (3S,4R)-3,4-dimethyl-L-pyroglutamic acid and (3S,4R)-3,4-dimethyl-L-glutamine.
  • Chiral N-heterocyclic carbenes (NHCs) as catalysts for the asymmetric dimerization of alkylarylketenes to give the corresponding α-quaternary β-alkylidenyl-β-lactones.

It is also used in the total synthesis of (−)-stemoamide and celogentin C.

Glucagon is conventionally regarded as a hormone, counter regulatory in function to insulin and plays a critical anti-hypoglycemic role by maintaining glucose homeostasis in both animals and humans. Glucagon performs this function by increasing hepatic glucose output to the blood
