3-(Methoxycarbonyl)-4-(3-methoxyphenyl)-4-(trifluoromethyl)-4-butanolide (4) was synthesised from 3-methoxyphenyl trifluoromethyl ketone (1).Hydrolysis of the lactone ester 4, followed by treatment with polyphosphoric acid, led to an intermediate lactone acid 3, which on heating with PCl5 gave the indenofurandione 5.
