合成路线1
该中间体在本合成路线中的序号：(II)Alkylation of silylated erythromycin oxime (I) with allyl bromide in the presence of t-BuOK provided allyl ether (II). After acid hydrolysis of the cyclo hexylidene ketal of (II), the oxime group was removed by treatment with NaHSO3 and formic acid to afford ketone (IV). Subsequent cleavage of the 3-O-cladinose unit of (IV) by hydrolysis with HCl furnished ketolide (V). The 2'-hydroxyl group of (V) was then protected by benzoylation with benzoic anhydride yielding (VI).

合成路线2
该中间体在本合成路线中的序号：(II)Alkylation of protected erythromycin (I) at the 6-hydroxyl group with allyl bromide provided ether (II). Hydrolysis of the cyclohexylidene ketal group of (II) with concomitant desilylation with AcOH gave (III). The oxime function was then hydrolyzed using either sodium bisulfite and formic acid or sodium nitrite and HCl to afford ketone (IV). Dihydroxylation of the allyl group of (IV) by means of N-methylmorpholine-N-oxide and a catalytic amount of OsO4, followed by oxidative cleavage of the resulting glycol (V) with NaIO4 produced aldehyde (VI). Alternatively, aldehyde (VI) was obtained by ozonolysis of the allyl ether (IV).
