enol ether of α-diazoacetoacetate is used for the annelation of aromatic oxo compounds. The method involves condensation with the oxo compound in the presence of TiCl4 followed by rhodium octanoate-catalyzed ringclosure to afford furan derivatives by direct carbene isertion and β-naphthol esters by a Wolff rearrangement pathway.

malonate, ethyl acetoacetate, and ethyl benzoylacetate under Knoevenagel conditions in the presence of molecularsieves to give the 1-naphthols (2), (5), and (6). Glass wool is a less effective catalyst for formation of (2). 3,3-Diethoxycarbonyl-1,1-diphenylpropene (4) is converted into the naphthol (2) in high yield by heating with molecularsieves but its saturated analogue (3) is unaffected.
