Abstract

Read online

An intramolecular-intermolecular cascade cyclization reaction via multi metal-carbene intermediates has been developed. This reaction uses catalytic amount of Nd(OTf)3, which actives both alkyne and aldehyde moieties. This protocol provides a novel strategy for the synthesis of phenanthro[9,10-b]furans. Keywords: Phenanthro[9,10-b]furan, Cyclization, Neodymium, Heterocycle, Cascade reaction
