VerwendenA cost-effective process for synthesizing daidzein was developed by Hai Cao and colleagues[1]. A two-step synthesis of daidzein (Friedel–Crafts acylation and [5+1] cyclization) was developed via the employment of trifluoromethanesulfonic acid (TfOH) as an effective promoting reagent. Due to the facilitating effect of TfOH, the Friedel–Crafts acylation was completed within 10 min at 90 °C and the [5+1] cyclization was completed within 180 min at 25 °C.
DefinitionChEBI: Trifluoromethanesulfonic acid is a one-carbon compound that is methanesulfonic acid in which the hydrogens attached to the methyl carbon have been replaced by fluorines. It is a one-carbon compound and a perfluoroalkanesulfonic acid. It is a conjugate acid of a triflate.
