3-Aroyl-5-hydroxyflavones: Synthesis and transformation into aroylpyrazoles

Treatment of 3-aroyl-5-benzyloxyflavones 4a-e with hydrazine afforded 3,5-diaryl-4-(2-benzyloxy-6-hydroxybenzoyl)pyrazoles 5a-e, together with 4-aroyl-5-aryl-3-(2-benzyloxy-6- hydroxyphenyl)pyrazoles 6a-e as minor products. The structures of all new compounds have been established by extensive NMR studies and the reaction mechanisms are discussed. Wiley-VCH Verlag GmbH, 69451 Weinheim, Germany, 2002.
