第三部分: 利用高效率銅催化分子內形成碳-氮鍵,利用起始物2’-bromo-2-cyanodipheny在少量的碘化銅和氫氧化鈉在100℃下可合成具高產率的菲啶酮衍生物結構。 The 1st Part: Variously synthetic methods of 3,3 spiro-oxindole derivatives were carried out and comparison of the mechanisms for different pathway was discussed. The 2st Part: An efficient copper-catalyzed intramolecular N-arylation was carried out by involving 2,2-substituted 2-(2-bromoaryl)acetamide to afford various substituted oxindoles with a small amount of Cu2O and benzene-1,2-diamine as catalytic system under aerobic conditions, which provided good to excellent yields with tolerance of wide variety of substrates. The 3st Part: An efficient copper-catalyzed intramolecular N-arylation was carried out by involving 2’-bromo-2-cyanodipheny to afford variously substituted phenanthridinones with a small amount of CuI and Sodium hydroxide at 100 oC, which provided good to excellent yields with tolerance of wide variety of substrates.
