- Facile access to chiral β-homoglutamic acid from 3-cyclohexene-carboxylic acid
-
A convenient, safe, and effective synthetic protocol for the synthesis of chiral β-homoglutamic acid was described. The strategy started from 3-cyclohexenecarboxylic acid, followed by three steps classic reaction including Curtius Rearrangement, oxidative
