A chemoselective domino annulation reaction of β-naphthols with methyl aryldiazoacetate is described. The gold catalyst promoted C–H functionalization of β-naphthols, whereas a rhodium or copper complex led to O–H insertion reactions. Consecutive intramol

Several new differentially substituted cyclobutenediones 4a-e have been prepared. Their thermal rearrangement to substituted naphthofuranones 5a-d is reported. This rearrangement involves an unprecedented intramolecular cyclization of a reactive bisketene 6, and forms the naphthofuranone system in good yield.
