Abstract

The syntheses of naphthol 7, naphthol 8, naphthol 11 and naphthol 12 are described, starting from juglone 13. C-Glycosylation of naphthol 8 with benzyl-protected glycosyl donor 10 using trimethylsilyl trifluoromethanesulfonate and silver perchlorate or boron trifluoride– diethyl ether affords rearranged product 36 in which the glycosyl donor has undergone an unusual 1, 6-hydride shift. Use of the corresponding naphthol 12 as the glycosyl acceptor ...
