合成路线1
该中间体在本合成路线中的序号：(XVII)The crossed aldol condensation of 7-iodo-2,3-dihydro-1H-indol-2-one (VIII) with the chiral oxazolidine-carbaldehyde (IX) by means of LDA in THF gives a mixture of (Z)-(X) and (E)-(XI) isomers, which is isomerized to the desired (E)-(XI) compound by treatment with I2 . The condensation of (XI) with the borinated tyrosine intermediate (VII) catalyzed with PdCl2(dppf)2 yields the diaryl compound (XII), whose ester group is hydrolyzed with LiOH in THF/water to afford the carboxylic acid (XIII). The condensation of (XIII) with L-asparagine tert-butyl ester (XIV) by means of EDC and 1-hydroxy-7-azabenzotriazole (HOAt) in THF provides adduct (XV), which is oxidized with OsO4, NMO and 1,4-bis(9-O-dihydroquinidinine)phthalazine ((DHOD)2PHAL) in tert-butanol/water to give the glycol (XVI). The cleavage of the oxazolidine ring of (XVI) by means of pyridinium p-toluenesulfonate (PPTS) yields the trihydroxy compound (XVII).
