Scandium triflate is an efficient catalyst for diazocarbonyl insertion reactions into O-H, S-H and carbamate N-H bonds, The O-H and S-H insertion reactions proceed at ambient temperature and selective O-H insertion is possible in the presence of a carbamate N-H, A novel approach to alpha-amino acids involving intramolecular carbene/N-H insertion as the key step has been demonstrated, (C) 1999 Elsevier Science Ltd.
