General description

Oxazole is the parent molecule for a large class of heterocyclic aromatic compounds. It is a weak base that can be used as an electron-deficient diene in the Diels-Alder cycloaddition reaction. It undergoes nitration, sulfonation, halogenation, Friedel-Crafts alkylation, and acylation.
