Abstract

A stereospecific synthesis of the tetrahydro-2H-indeno[1,2-b]furan skeleton, which is embedded in bioactive aromatic strigolactones such as GR24, is realized by a nickel-mediated tandem cross-coupling for the first time. The observed cis-stereoselectivity during the intramolecular formation of the Csp3–Csp2 bond is rationalized through conformation analysis and DFT calculations.
