概要
- 論文の詳細を見る
4,5-Dialkoxy-2-nitrobenzaldehydes (IXa to IXd) were condensed with anilines (Xa to Xd), followed by immediate treatment with triethyl phosphite, to afford 5,6-dialkoxy-2-aryl-2-H-indazoles (VIa to VIl) in a fair yield. Nuclear magnetic resonance and infrared spectra of the indazoles were discussed.
