Abstract

A number of 3-bromo-5,6-dihydro-4H-1,2-oxazine N-oxides have been synthesized and subjected to [3+2] cycloaddition with alkenes affording various types of products: 3-vinyloxazolines, isoxazoline N-oxides, and 3-functionalized 1,2-oxazine N-oxides.

Key words

1,2-oxazine N-oxide - isoxazoline - cycloaddition - nitronates - nitroso acetals
