Abstract
N-[2-(œ-Bromoacetyl)phenyl]imides (prepared in two steps from 2-aminoacetophenone) gave upon treatment with sodium azide fused azidoquinolines via an intamolecular cyclization. Reaction of the above azides with phosphines gave N-heteryliminophosphoranes. The IR, 1H-, 13C-, and 31P-NMR and MS spectra of these compounds as well as the X-ray crystal structure of two of them is reported
The reaction of hydrazones of 2-aminoacetophenone with triphosgene in dichloromethane or benzene in the presence of triethylamine gave quinazolines, pyrazolo[1,5-c]quinazoline and spiro…
Essential oils (EOs) from the stems and leaves of Origanum vulgare L. grown in Saudi Arabia and Jordan were analyzed by gas chromatography–mass spectrometry (GC–MS) and GC–flame ionization…
