Copper and secondary amine‐catalyzed pyridine synthesis from o‐acetyl oximes and α,β-unsaturated aldehydes

A. Acetophenone O-acetyl oxime (1). A 250-mL, two-necked roundbottomed flask equipped with a Teflon-coated magnetic stir bar (oval, 20 x 10 mm) is charged with acetophenone (9.33 mL, 80.0 mmol, 1 equiv) (Note 2), pyridine (18 mL, 223 mmol, 2.8 equiv) (Note 3), ethanol (40 mL) (Note 4), and hydroxyl...
