Simple Synthesis of 2,2'-Bisindole from Indigo and Its Application for the Syntheses of Indolo[2,3-a]pyrrolo[3,4-c]carbazole-5,7-(6H)dione and -5-(6H)one Derivatives
摘要:
Indigo was converted to 2,2'-bisindole, from which 6-substituted indolo[2,3-a]pyrrolo[3,4-c]carbazole-5,7-(6H)dione and -5-(6H)one derivatives were prepared in short steps. Bromination of 6-methylindolo[2,3-a]pyrrolo[3,4-c]carbazole5,7-(6H)dione is also reported.

Herein we describe a Cu-catalyzed radical addition and oxidation cascade reaction for the chemo/regioselective synthesis of unsymmetrical indole trimers (isotriazatruxenes, i-TATs) from easily available starting materials. The i-TATs exhibited blue fluorescence in various solvents with different fluorescence intensities and showed good structural expansibility. A wider range of products could be used
在这里,我们描述了一种铜催化的自由基加成和氧化级联反应,用于从容易获得的起始材料化学/区域选择性合成不对称吲哚三聚体(异三氮杂环己烯, i -TAT)。i- TATs在不同荧光强度的各种溶剂中呈现蓝色荧光,并表现出良好的结构扩展性。通过开发合适的衍生物,可以将更广泛的产品用于光电材料。
Short Step Syntheses of Indolo[2,3-a]carbazoles Carrying an Alkyl, Allyl, or a Glycosyl Group at the 11-Position and a Novel 6,7-Dihydro-13H-cyclopentano[mn]indolo[3,2-c]acridine Derivative
Novel 1-alkyl-, 1-allyl-, and 1-beta-glycosyl-2,2'-biindolyls are prepared. Their Diels-Alder reaction produced 11-alkyl-, 11-allyl-, and 11-beta-glycosylindolo[2,3-a]carbazoles. Formation of a novel 6,7-dihydro-13H-cyclopentano[mn]indolo[3,2-c]acridine derivative is also reported.
Reduction of Indigo: Simple Syntheses of 3-Acetoxy-, 1-Acetyl-2,3-dihydro-, 3-Acetoxy-3'-acetyl-, 3-Acetoxy-1,3'-diacetyl-2,2'-bisindoles, and 2,2'-Bisindole

Indigo was converted to 2,2'-bisindole by the direct reduction with zinc in acetic acid and acetic anhydride under argon or hydrogen atmosphere. Reduction with tin and iron afforded 3-acetoxy-2,2'-bisindole predominantly. Useful building blocks such as 1-acetyl-2,3-dihydro-, 3-acetoxy-3'-acetyl-, and 3-acetoxy-1,3'-diacetyl-2,2'-bisindoles were also produced depending on metal and reaction conditions.
