ABSTRACT:
N-acyl sydnonimines of the formula: ##STR1## wherein R is phenyl, .beta.-phenylethyl, dl-.alpha.-methyl-.beta.-phenylethyl or l-.alpha.-methyl-.beta.-phenylethyl; R' is hydrogen, phenyl; X is a lower alkyl, phenyl, ##STR2## wherein R" is hydrogen, a halogen, a lower fluorinated alkyl; R'" is hydrogen, a halogen, a lower alkyl; when R is dl-.alpha.-methyl-.beta.-phenylethyl, R' is H, R" is Cl, R'" is only Cl, while when R' is H, X is NHC.sub.6 H.sub.5 R is only l-.alpha.-methyl-.beta.-phenylethyl; when X is phenyl, R and R' are each phenyl only.
The method for preparing sydnonimine N-acylderivatives comprises reacting N-nitrosoderivatives of N-substituted nitriles of .alpha.-aminoacids of the formula: ##STR3## wherein R is phenyl, .beta.-phenylethyl, di-.alpha.-methyl-.beta.-phenylethyl or l-.alpha.-methyl-.beta.-phenylethyl; R' is H, phenyl; when R' is phenyl R is phenyl only, with an acylation agent in a solvent medium in the presence of a basic-character catalyst, followed by isolation of the desired product.
