An efficient and atom-economic one-pot synthesis method for isoindolo[2,1-a]indol-6-ones has been developed, utilizing CuI/Pd(OAc)(2)-catalyzed intramolecular hydroamidation of alkynyl group and C-H dehydrogenative coupling of ortho-alkynyl-N-arylbenzamides. Oxygen is used as the oxidant and water is the sole by-product in this transformation. The reaction exhibits excellent tolerance towards various functional groups and provides isoindolo[2,1-a]indol-6-ones in good to high yields.
An efficient, atom-economic and one-pot synthesis of isoindolo[2,1-a]indol-6-ones via CuI/Pd(OAc)(2)-catalyzed intramolecular hydroamidation of alkynyl group, and C-H dehydrogenative coupling of ortho-alkynyl-N-arylbenzamides has been developed. This transformation occurs with the use of oxygen as the oxidant, and water is the only by-product. The reaction shows a high tolerance to a variety of functional groups, and affords isoindolo[2,1-a]indol-6-ones in good to high yields.
