Efficient and Uncatalyzed Synthesis of Highly Functionalized New Symmetrical Indeno1,2-bpyrroles via a One-Pot Four-Component Reaction

摘要

abstract_textpA facile, efficient and un-catalyzed approach for the synthesis of new symmetrical highly- substituted indeno [1,2-b]pyrrole derivatives through four-component reaction, involving, primary amines, diamine, diketene, and ninhydrin in CH2Cl2 at ambient temperature is reported. This approach enjoys merits such as being done in the absence of catalyst at ambient temperature, giving good to excellent yields, completed in short reaction times, and showing a wide functional group tolerance./p/abstract_text
