Benzothiete () undergoes cycloaddition reactions with hetero dienophiles with NN-, NO- or CO- double bonds, leading to six-membered heterocyclic ring systems of 2H-3,4-dihydro-1,2,3-benzothiadiazine (), 4H-3,1,2-benzoxathiazine () and 4H-3,1-benzoxathiin.
苯并噻吩()与具有NN-,NO-或CO-双键的杂二烯亲二烯体进行环加成反应,形成2H-3,4-二氢-1,2,3-苯并噻二嗪的六元杂环系统(),4H- 3,1,2-苯并恶嗪()和4H-3,1-苯并恶嗪。
