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.

Condensation of 2,5-dichlorobenzoyl chloride (I) with glycine (II) in the presence of NaOH in H2O/THF gives 2-(2,5-dichlorobenzoylamino) acetic acid (III), which then couples with the 1,3,2-benzodioxaborolyl butanamine derivative (IV) by means of TBTU and DIEA in DMF to yield peptide (V). O-Deprotection of 1,3,2-benzodioxaborolane (V) by means of HCl and 2-methylisopropyl boronic acid in methanol/hexane affords boroxin derivative (VI), which is finally esterified with citric acid (VII) in THF or MIBK or acetonitrile or 2-Me-THF or acetone or EtOAc .
