Synthesis of 4-Oxoindeno[1,2-b]pyrroles through Copper-Catalyzed Tandem Reactions of 1-(2-Haloaryl)enones with Isocyanides
Copper-catalyzedtandemreactions of 1-(2-haloaryl)-enones with isocyanides for the synthesis of 4-oxoindeno[1,2-b]pyrroles are described. Highly reactive cyclic organocopper intermediates are generated in the copper-catalyzed [3+2]-cycloaddition reactions of isocyanides to double or triple bonds. Successful intramolecular trapping of the organocopper intermediates led to the efficient formation of
