11 - 140A Novel and Efficient 2,4,6-Trisubstituted Pyridine Ring Synthesisvia α-Benzotriazolyl Ketones. — Reaction of chalcones (I) withα-benzotriazolylketones yields 2,4,6-triarylated pyridines. The proposedintermediate 1,5-diketone type (VIII) can be prepared independently. — (KA-TRITZKY, ALAN R.; ABDEL-FATTAH, ASHRAF A.
