%X 4-(6&#8242;-Methoxy-3&#8242;,4&#8242;-dihydronaphthalen-1&#8242;-yl)butan-2-one (6b) was condensed with ethyl cyano-acetate to give a mixture of the geometric isomers of the &#945;, &#946; unsaturated cyano ester (8), reaction of which with the anion derived from cyanoacetamide gave the Guareschi imide (7). Attempts to hydrolyse this to 3-[2&#8242;-(6&#8243;-methoxy-3&#8243;,4&#8243;-dihydronaphthalen-1&#8243;-yl)ethyl]-3-methylglutaric acid (4) gave only polymeric material. The preparations of 2,2-ethylenedioxy-4-(6&#8242;-methoxynaphthalen-1&#8242;-yl)butane (5a) and the corresponding butanone (5b) are also described.
