Synthesis of Some New 3,4-DiarylsydnonesThe synthesis of some new sydnones 4 is described. Their characteristic absorption maxima, mass spectroscopic fragmentation and C=O-valence vibrations are given. The sydnones 4 are synthezid by nitrosation of C, N-diarylglycines 3 (from strecker synthesis) and subsequent cyclization with Ac2O. The primarily formed C,N-diaryl-α-aminoacetic acid nitrils (1) are decomposed with conc. HCl yielding glycines (3) in good yields.
