   Compounds of the mesoionic class have interesting structural features provided by their betaine-like character. Mesoionic compounds (MICs) consist of a five-membered heterocyclic ring associated with a sextet of p and π electrons, in which both positive and negative charges are delocalized, have been known for more than a century [1,5]. In recent times, MICs have attracted the attention of chemists particularly because of the bonding aspects associated with their unusual structure which can be regarded as mesomeric heterocyclic betaines, strongly stabilized by π-electron delocalization and having large dipole moments [6]. The association of these characteristics suggests a high probability of strong interactions with biomolecules such as DNA and/or proteins [7]. Although mesoionic compounds are internally charged, they are neutral overall, and can therefore cross biological membranes in vivo [8]. The synthetic approaches to mesoionic heterocycles by 1,3 dipolar cycloaddition reactions are mostly those concerning münchnones (1,3-oxazolium-5-olates) and the newer isomünchnones (1,3-oxazolium-4-olates). Some work involving the mesoionic sydnones (1,2,3-oxadiazolium-5-olates), thiomünchnones (1,3-oxathiolium5-olates) and thioisomünchnones (1,3-thiazolium-4-olates) have also appeared [9-12].
