合成路线3
该中间体在本合成路线中的序号:(VII)The peroxidation of 1,4-diphenyl-1-cyclopentadiene (I) with O2, white light and activated by tetraphenylporphyrin in dichloromethane gives the peroxide (II), which is condensed with cyclohexane-1,4-dione (III) by means of trimethylsilyl trifluoromethanesulfonate in dichloromethane, yielding the adduct (IV). The reductocondensation of (IV) with N-(7-chloroquinolin-4-yl)ethylenediamine (V) by means of NaBH(OAc)3 in dichloromethane affords the tricyclic trioxane (VI), which is finally treated with citric acid in acetone to provide the target citrate. The intermediate N-(7-chloroquinolin-4-yl)ethylenediamine (V) has been obtained by reaction of 4,7-dichloroquinoline (VIII) with ethylenediamine by means of NaOH at 85 C.
