Abstract

This paper describes the study of the reaction between 1, 8-diazafluoren-9-one (DFO) with the amino acid L-alanine in methyl alcohol. Particular interest was paid to the possible role of the solvent which appears to react with the DFO to form a hemiketal that is the reactive species. A potential reaction pathway is proposed based on the current data collected. The reaction intermediates and products were identified by a variety of spectroscopic methods including mass spectrometry (MS), nuclear magnetic resonance (NMR) spectroscopy, and X-ray crystallography.
