Several novel benzofuran-containing spirolactones were synthesized and characterized using copper-catalyzed heterodimerization of 1,2-diarylcyclopropenones, and followed by sequential intramolecular cyclopropene ring opening and oxidative cyclization. (C) 2014 Elsevier Ltd. All rights reserved.

A Rh(III)-catalyzed aryl C-H bond insertion into cyclopropenones via a C-H activation pathway has been reported. A series of arenes bearing directing groups such as 2-pyridyl, 2-pyrimidyl, N-pyrazyl, and oxime can be applicable, providing chalcones in excellent yields under mild conditions. Several possible Rh(III) intermediates in this reaction were investigated.
