The silyl 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 ring closure to afford fur
α-Naphthol Synthesis via Knoevenagel Condensation in the Presence of Molecular Sieves

Diphenylethanal condenses with diethyl malonate, ethyl acetoacetate, and ethyl benzoylacetate under Knoevenagel conditions in the presence of molecular sieves 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 molecular sieves but its saturated analogue (3) is unaffected.
