ChemInform Abstract: A Simple Metal‐Free Synthesis of 2, 4, 5‐Trisubstituted Pyridines and Pyridine N‐Oxides by [2 + 2] Cycloaddition of Enaminones to Propyne Iminium Salts. Issue 1 (January 2015) - Bezensek, Jure
Abstract A simple, metal‐free method for the synthesis of the title pyridines is developed, which complements the existing methods of 2‐pyridine synthesis by coupling reactions of organometallic reagents.
