## Abstract The diazo ketones derived from Z‐ and Boc‐protected alanine, valine, and alanyl‐alanine (1–5) were decomposed by catalytic amounts of silver benzoate/Et~3~N in the presence of polyfunctional nucleophiles such as 3‐methyl‐1,3‐butanediol, 2‐aminoethanol, carbohydrates (xylofuranose and su
