The relative importance of three different routes for the N-nitrosation of amino acids (nitrosation by N 2 O 3 , by and by intramolecular migration of the nitroso group from the initially nitrosated carboxylate group) was investigated for methylaminobutyric acid, methylaminoisobutyric acid, azetidin
