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 earbamate N-H. A novel approach to a-amino acids inv
