✦ Synopsis

Reaction of Pyrylium Salts with Nucleophiles. Part 25. Formation of Pyridine-1-oxides, 2-Isoxazolines and 1-Pyrazoline-1-oxides.

-The competitive formation of pyridine-1-oxides and 2-isoxazolines from reaction of pyrylium salts with hydroxylamine is investigated. The synthetic value of pyrylium salts for the preparation of 2-isoxazolines is emphasized for the first time.
