Nd(OTf)3-Catalyzed Intramolecular-intermolecular Cascade Cyclization Reaction: An Access to Phenanthro[9,10-b]furan Derivatives

Publication date: Available online 12 June 2019Source: Journal of Saudi Chemical SocietyAuthor(s): Hao Dong, Dawen Xu, Wangsheng Liu, Yaopeng Zhang, Hao GuoAbstractAn 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.Graphical abstract
