Journey describing applications of oxone in synthetic chemistry

The nitroso ene reaction: a regioselective and stereoselective allylic nitrogen functionalization of mechanistic delight and synthetic potential

Development and applications of amino acid-derived chiral acylnitroso hetero diels-alder reactions

Some α- and β-halonitrosoalkenes 1 have been synthesized and characterized. The halogen atoms of the oxime precursors 2 can be substituted by alkoxy groups. Two kinds of cycloaddition reaction of 1 have been observed: (i) reaction of the NO group with dienes gives 3, 6-dihydrooxazine derivatives 6 which isomerise to epoxyepimines 7 in most cases of β-substituted nitrosoalkenes; (ii) if 4, 5-dihydrooxazines 22 are obtained, the cycloaddition of the nitrosoalkenes as 4π-component is presumed.
