Reaction Conditions:

at 170; for 2.5 h;

Steps:

Synthesis of 2-imidoalkanecarboxylic acids 6 from α-aminoacids

General procedure: The synthesis of 2-imidoalkanecarboxylic acids 6 wascarried out based on the modified procedure described byMcKenzie and Walker [32]. The corresponding α-amino acid(10 mmol) was heated with phthalic or succinic anhydride(11 mmol) at 170 °C or 140 °C under reduced pressure for thetime given in Table 1.
