A facile synthesis of 2-substituted isoflavones for immunoassay: Assembly of the isoflavonoid skeleton by means of a novel cyclisation reaction

For the purpose of the development of immunoassays for wide-scale screening, isoflavones suitable for attachment to a hapten were prepared. A new cyclisation reaction allowed the direct conversion of 2- (acyloxy)deoxybenzoins to 2-alkylisoflavones by treatment with chlorotrimethylsilane and triethylamine in dimethylformamide.
