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.
