Significant facilitation of metal-free aerobic oxidative cyclization of imines with water in synthesis of benzimidazoles

One-Pot Synthesis of Benzo[4,5]imidazo[2,1-a]isoquinolines and Isoquinolino[3,4-b]quinoxalines via Tandem Cyclization Strategies

Two operationally simple one-pot protocols have been developed for the synthesis of amino-functionalized benzo[4,5]imidazo[2,1-a]isoquinolines and isoquinolino[3,4-b]quinoxalines. Optimization data and substrate scope for these atom-economical transformations, which engage commercially available o-phenylenediamines and o-cyanobenzaldehydes, are discussed.

Diversity oriented synthesis of β-carbolinone and indolo-pyrazinone analogues based on an Ugi four component reaction and subsequent cyclisation of the resulting indole intermediate

One pot two step synthesis of β-carbolinone and indolo-pyrazinone analogues via acid mediated cyclisation of Ugi intermediate has been developed with a wide substrate scope.

Lewis acidic ionic liquids of crown ether complex cations: preparation and applications in organic reactions

New Lewis acidic ionic liquids composed of crown ether complex cations were designed, synthesised and characterised by Raman, MS, FT-IR, TGA-DSC and elemental analysis. They have been successfully used in various organic reactions as catalysts.

Metal-templated synthesis of intertwined, functionalized strands as precursors to molecularly woven materials

A novel approach toward molecularly woven materials is presented, based on metal-templated precursors containing intertwined strands with functional endings.
