合成路线1

The reaction of desoxyanisoin (I) with hydroxylamine in methanol gives the corresponding oxime (I), which is cyclized with ethyl acetate (III) by means of n-butyllithium in THF yielding 3,4-di(4-methoxyphenyl)-5-methylisoxazole (IV). Finally, this compound is condensed with CO2 by means of n-butyllithium in THF.
