Eremeev, A. V.,Solodin, I. V.,Polyak, F. D.
, p. 1023 - 1024 (2007/10/02)
The corresponding azide was obtained by nitrosation of 1-benzylaziridine-2-carboxylic acid hydrazide.Reaction of the azide with methyl esters of amino acids gave N-(1-benzyl-2-aziridinylcarbonyl)-substituted methyl esters of amino acids.
