Regioselektive Zinn(II)chlorid-induzierte N-Aralkoxy-alkylierung am 2,3-Dimethylindol
2,3-Dimethylindole (1) reacts by tin(II)chloride catalysis with arylaldehydes in dichloromethane, which contains 0.2% ethanol, regioselectively to the indol-1-yl-aryl-ethoxy-methanes3 a, 3 b.
Zur Konstitutionsaufklärung trisubstituierter Indolderivate: NMR-spektroskopische Untersuchung von Bis(2,3-dimethyl-6-indolyl)-arylmethanen
The application of combined1H- and13C-NMR-technics is used exemplarily for the elucidation of the type of substitution at the phenyl nucleus of indoles in 6,6′-bis-indolylarylmethanes (1,2). These methods can be applied in general to analogous structure problems.
Zur protonenkatalysierten Aralkylierung von 1,2,3-Trimethylindol und 1,2,3,4-Tetrahydrocarbazol mit Arylaldehyden
1,2,3-Trimethylindol (2) liefert mit Benzaldehyden die Kondensationsprodukte 5 und 6, wahrend aus den NH-Indolen 1 und 3 die Verbindungen 7 und 8 entstehen. Proton-catalyzed Aralkylation of 1,2,3-Trimethylindole and 1,2,3,4-Tetrahydrocarbazole with Arylaldehydes Reaction of 1,2,3-trimethylindole (2) with benzaldehydes leads to the condensation compounds 5 and 6, the NH-indoles 1 and 3, however, give 7 and 8.
