Studies on Nitrogen-Containing Heterocyclic Compounds. XLVIII. Reissert Type's Reaction of N-Acylbenzo [f] quinolinium Chloride and Trialkyl Phosphite (1)

Abstract

The reaction of benzo [f] quinoline (1) with various acyl chlorides and trimethyl phosphite in the presence of sodium iodide gave the corresponding N-heterocyclic α-phosphonate (2) and γ-phosphonate (3). In the similar reaction using bulky phosphites, the ratios [2/3] were changed by a steric effect between the benzo [f] quinoline and the trialkyl phosphite.
