The NCAs of the N-benzyl derivatives of 8-alanine, j3-nL-aminobutyric acid, and j3nkaminoisobutyric acid (nonplanar six-membered rings) were prepared by reacting the corresponding N-chloroformyl derivatives, obtained on reaction of the N-benzyl amino acids with phosgene, with triethylamine. Contrary
