A metal-free, one-pot, iodine-mediated, microwave-assisted cyclization of 1-(1′-arylvinyl)-2-naphthols (ortho-vinylnaphthols) into 1-arylnaphthofurans is developed. The 1-arylnaphthofurans are isolated in good to excellent yields (65-90%) using two equiva

The ruthenium(II)-catalyzed annulation of vinylnaphthols and alkynes is described. The reaction proceeds through C?H activation, dearomatization, and alkyne insertion. This reaction affords spiro-pentacyclic naphthalenones that have biological significance in good yields.

A highly atom-efficient synthetic protocol for hydroarylation of terminal-aryl alkynes and styrene through the regioselective C–C bond formation via the electrophilic addition of naphthols and substituted phenols has been developed using alumina-sulfuric acid as a heterogeneous supported solid acid catalyst. This methodology shows excellent regioselectivity and affords the desired product in good to excellent yield. The heterogeneous catalyst can also be recycled efficiently without much loss of activity.
A simple and efficient synthesis of 2,3-diarylnaphthofurans using sequential hydroarylation/Heck oxyarylation
Rao, V. Kameshwara,Shelke, Ganesh M.,Tiwari, Rakesh,Parang, Keykavous,Kumar, Anil

An efficient and simple strategy has been developed for the synthesis of 2,3-diarylnaphthofurans using sequential hydroarylation of naphthols and alkynes in the presence of In(OTf)3 under microwave irradiation followed by one-pot Heck-oxyarylat
Gallium(III) chloride catalyzed hydroarylation of arylacetylenes with naphthols and phenols: A facile synthesis of vinylarenes
Yadav, Jhillu S.,Subba Reddy, Basi V.,Sengupta, Sandip,Biswas, Swapan Kumar
experimental part, p. 1301 - 1304 (2009/12/07)
Arylacetylenes undergo smooth hydroarylation with naphthols and phenols in the presence of 10 mol% of gallium(III) chloride in refluxing toluene to afford the corresponding 2-vinylnaphthols and -phenols in good yields with high regioselectivity. Similarly, styrenes undergo hydroarylation with naphthols and phenols to provide substituted naphthols and phenols. Georg Thieme Verlag Stuttgart.
