Descrizione

 

Doebner-Miller reaction the 4- nitrocinnamaldehyde and 2-methylaniline in concentrated HC1 give the corresponding 8-methyl-2-phenylquinoline (3: R = 4'-N02) directly. The asymmetric Friedel-Crafts-type alkylation in aqueous media reaction of 4-Nitrocinnamaldehydr with N-methyl indole using trifluoroacetic acid (TFA) salt of the PEG-PS-supported prolyl peptide having the polyleucine tether as a catalyst. 4-Nitrocinnamaldehyde has been used in the preparation of 2, 2?-[(E)-3-(4-nitrophenyl) prop-2-ene-1,1-diyl] bis(3-hydroxy-5, 5-dimethylcyclohex-2-en-1-one).

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Anwendungen
Bei der Doebner-Miller-Reaktion entsteht aus 4-Nitrocinnamaldehyd und 2-Methylanilin in konzentrierter HCl das entsprechende 8-Methyl-2-phenylquinolin (3: R = 4′-N02) direkt. Bei der asymmetrischen Friedel-Crafts-Alkylierung in wässrigem Medium reagiert 4-Nitrocinnamaldehyd mit N-Methylindol unter Einsatz des Trifluoressigsäuresalzes des von PEG-PS unterstützten Prolylpeptids, mit dem Polyleucin-Tether als Katalysator. 4-Nitrocinnamaldehyd wurde zur Herstellung von 2, 2′-[(E)-3-(4-nitrophenyl) prop-2-en-1,1-diyl]-bis-(3-hydroxy-5, 5-dimethylcyclohex-2-en-1-on) verwendet.
