= S) as common synthons in the efficient synthesis of various dibenzoxepino[4,5‐ and dibenzothiepino[4,5]‐fused five‐membered heterocycles: [2,3] fused thiophene (II), [3,4] fused thiophene (III), furan (IV), pyrrole (V), imidazole (VI), pyrazole (VII), oxazole (VIII), and thiazole (IX). The potential of I to be converted into reactive intermediates that readily undergo heteroaromatic annulation reactions
本综述着重于二苯并[ b,f ] oxepin-10(11 H)-one(I,X = O)和二苯并[ b,f ] thiepin-10(11 H)-one(I,X = S)作为有效合成各种二苯并噻吩并[4,5]和二苯并噻吩并[4,5]稠合的五元杂环的常用合成子:[2,3]稠合噻吩(II),[3,4]稠合噻吩(III) ,呋喃(IV),吡咯(V),咪唑(VI),吡唑(VII),恶唑(VIII)和噻唑(IX)。我的潜力通过适当的双亲核剂与环缩合反应转变成易于发生杂芳族环化反应的反应性中间体,可以形成一系列列举的官能化二苯并[ e,h ] azulene [4]结构(II,III,IV,V,VI,VII,VIII,IX)。可以进一步修饰二苯并[ e,h ] azulenes作为杂环四环骨架,以获得具有改变的理化和生物学特性的化合物。J.杂环化学。(2012)。
