SYNTHESIS, SPECTROSCOPIC STUDIES, AND X-RAY CRYSTAL STRUCTURE OF N-HETERYLIMINOPHOSPHORANES
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.

Abstract An intramolecular Wittig reaction of some substituted aminoacetophenones was used for the synthesis of novelquinolinederivatives. In addition, the base induced cyclization of the aminoacetophenones was investigated. The IR and NMR spectra of the quinolinederivatives are reported.
