Реферат:
N-(2-Oxoalkyl)-2-chloroacetohydroxamic acids were obtained by acylation of 1,2-hydroxylamino ketones with chloroacetyl chloride. Their reaction with urotropin and sodium azide gives urotropinium salts and acetoxyhydroxamic acid azides. 1-Hydroxy-2-oxo-1,2,3,6-tetrahydropyrazines were obtained by treating N-(2-oxoalkyl)-2-chloroacetohydroxyamic acids with ammonia, and also by reacting the urotropinium salts and azides of acetohydroxamic acids with hydrochloric acid and triphenylphosphine, respectively. The reaction of N-(1-methyl-2-oxo-2-phenylethyl)-2-chloroacetohydroxamic acid with urotropin in an acid medium leads to the formation of 6-methyl-2-oxo-5-phenyl-1,2-dihydropyrazine. © 1986 Plenum Publishing Corporation.
