설명

일반 설명

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.

애플리케이션

Oxazole can be used:

• in the intramolecular Diels–Alder (IMDA) cycloaddition reaction to synthesis natural products
• as a precursor in the ring opening, nucleophilic addition and recyclization as well as [2 + 2], [3 + 2], and [4 + 2] cycloaddition reactions
