摘要:
N-[2-(alpha-Bromoacetyl)phenyl]imides (prepared in two steps from 2-aminoacetophenone) gave, upon treatment with sodium azide, fused azidoquinolines via an intramolecular cyclization. Reaction of the above azides with phosphines gave N-heteryliminophosphoranes. The IR, H-1-, C-13-, and P-31-NMR and MS spectra of these compounds as well as the x-ray crystal structure of two of them is reported.
