The three-component reaction resulted in the unique spiro[indoline-3,4′-naphtho[1,2-b]furan] derivatives, which were converted to spiro[indoline-3,2′-naphthalen]-4′-yl acetates by acylation and alkoxy-substituted spiro[benzo[h]chromene-5,3′-indolines] by acid catalyzed etherification.

Borinic Acid

Diphenylborinic acid catalysis enables the direct, stereo- and site-selective coupling of glycosyl donors with ceramide lipids. The β-1,1′-linkages accessed through this method are characteristic of mammalian glycosphingolipids that play diverse roles in physiology, human health and disease.
