A comparative study of the relative reactivity of bisglycinatocopper(II) and <I>N</I>-pyruvylideneglycinatoaquocopper(II) in a base-catalyzed condensation reaction with aldehydo sugar derivatives concluded that the latter complex is much more reactive than the former. This reaction was found to proceed with a considerably high stereoselectivity to afford blocked 2-amino-2-deoxyaldonic acids with a <I>threo</I> configurational relationship between <I>C</I>–2 and <I>C</I>–3, and between <I>C</I>–3 and <I>C</I>–4. The resultant products were converted to the corresponding free 2-amino-2-deoxyaldonic acids in good yields by deblocking them with Amberlite IR-12OB(H form).
