Abstract

1,3-oxazinium 4-olates are known as six-membered mesoionic ring systems composing of nitrogen and oxygen atoms that undergo various 1,4-dipolar cyclo-cycloaddition reactions, for example, with alkenes, ketones [1,2]. According to the classification by Ollis, Stanforth, and Ramsden, these mesoionic compounds should be regarded as cross-conjugated mesomeric betaines (CMB) who’s their structures have no conjugation between anionic and cationic delocalized systems of the molecules [2]
