Novel Strategy for Synthesis of Substituted Benzimidazo[1,2-a]quinolines
摘要:
An efficient method for the synthesis of benzimidazo[1,2-a]quinolines under transition-metal-free conditions has been developed through a cascade reaction involving sequential aromatic nucleophilic substitution and intramolecular Knoevenagel condensation reactions. This method is applicable for the synthesis of a wide range of benzimidazo[1,2-a]quinoline derivatives from readily available 2-fluoroarylaldehyde and benzimidazole substrates.

A series of potentially bidentate benzimidazolyl ligands of the type (Bim)CH2D (where Bim = benzimidazolyl and D = NMe2 L1, NEt2 L2, NPr2i L3, OMe L4 and SMe L5) has been reacted with Ti(NMe2) 4 to give five- and six-coordinate Ti(IV) complexes of the type [(Bim)CH2D] Ti(NMe2)(3) and [(Bim)CH2D](2)Ti(NMe2)(2), respectively. The X-ray structures of [(Bim)CH2OMe] Ti(NMe2)(3), [(Bim)CH2NMe2](2)Ti(NMe2)(2) and [(Bim)-CH2OMe)](2) Ti(NMe2)(2) are reported along with an evaluation of their behavior in ethylene polymerization.

Some 2-substituted benzimidazole-N-carbamates were synthesized and tested in vitro for antiviral activity. Two derivatives were active at noncytotoxic concentrations. The results confirmed the importance of the substituents at the 2-position of benzimidazole; an isopropylcarboxamide group led to the best activity. (C) 2000 Elsevier Science S.A.

Synthesis of 5-Aminobenzoimidazo[1,2-a]Quinoline Derivatives Through One-Pot Two-Step Cascade Reaction
An efficient method for the synthesis of 5-aminobenzimidazo[1,2-a]quinolines with high diversity has been developed through a cascade reaction involving sequential aromatic nucleophilic substitution and the Dieckmann Thorpe cyclization. This method is applicable to the synthesis of a wide range of 5-aminobenzimidazo[1,2-ca]quinoline derivatives from readily available 2-fluoroarylnitriles and benzimidazole substrates. Moderate light emission was observed for some 5-aminobenzimidazo[1,2-a]quinolines.
