• N-Protected amino acids can be converted to carboxamidomethyl (CAM) esters via their Cs salts. The CAM protecting group can be cleaved under mildly basic conditions, but is stable to the conditions used for the cleavage of t-butyl, Boc, Fmoc or Cbz protecting groups: Tetrahedron Lett., 24, 5219 (1983).
