Abstract

Synthesis and application of azacycloalk-1-enefused oxazol-3-ium salts are summarized. The microreview covers all synthetic methods for obtaining 6,7-dihydro-5H-pyrrolo[2,1-b]oxazol-4-ium and 5,6,7,8-tetrahydrooxazolo[3,2-a]pyridin-4-ium derivatives that have been classified in two distinct categories: cyclization leading to the formation of azacycloalk-1-ene ring and
cyclization leading to the formation of oxazole ring. Application of these azacycloalk-1-enefused oxazol-3-ium salts has been discussed.
