合成路线:The condensation of indane-1,3-dione (I) with benzaldehyde (II) by means of piperidine in refluxing benzene gives 2-benzylideneindane-1,3-dione (II),which is treated with H2O2 and NaOH in methanol to yield the epoxide (IV).The condensation of (IV) with N-(3,4-dichlorophenyl)maleimide (V) (obtained by condensation of 3,4-dichloroaniline (VI) with maleic anhydride (VII) in diethyl ether) in refluxing benzene affords the title product as a mixture of two diastereomeric racemates that are separated by column chromatography.
