Abstract
Conclusions1.Hydrogenation of ethyl 5-cyano-2-oximinovalerate in acetic anhydride at atmospheric pressure in the presence of strong base leads to a quantitative yield of the ethyl ester of α,ε-diacetyllysine.2.Selective reduction of the cyano and oximino groups in ethyl 5-cyano-2-oximinovalerate has been shown in the presence of powdered Ni, Cu-Ni, and LaNi5H6.6 catalysts.3.Hydrogenation of ethyl 5-cyano-2-oximinovalerate on Raney Ni at atmospheric pressure in dioxan with addition of acetic anhydride leads to a 50% yield of diacetyllysine.
