Lai, Ellen C. K.,Mackay, Donald,Taylor, Nicholas J.,Watson, Kenneth N.

, p. 1497 - 1506 (2007/10/02)

The bicyclic 1,2-oxazines derived from the cycloaddition of α-nitrosostyrene to either 2,5-dimethylfuran (11) or cyclopentadiene (15) react further with nitrosostyrene or other nitrosoalkenes.Only 3 + 2 addition is observed with (11) to give the tricyclic
