The synthesis of N‐[N‐(2‐chloroethyl)‐N‐nitrosocarbamoyl]amino acids and their anilides, congeners of N‐(2‐chloroethyl)‐N‐nitrosoureas, as potentialantineoplastic substances is reported. N‐[N‐(2‐chloroethyl)‐N‐nitrosocarbamoyl]amino acids are prepared by reaction of amino acids with N‐(2‐chloroethyl)‐N‐nitrosocarbamoyl azide. Corresponding anilides and toluidides are obtained by condensation of the
)‐N'‐nitrosocarbamoyl]aminoacidamides and esters as potential antineoplastic substances are reported. N‐[N'‐(2‐chloroethyl)‐N'‐nitrosocarbamoyl]aminoacids (with the exception of the glycine derivative) were prepared by reaction of 2‐chloroethyl isocyanate with the sodium salt of an aminoacid in a heterogenous medium followed by nitrosation with sodium nitrite under acidic conditions.
