合成路线2

该中间体在本合成路线中的序号:(I)

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).
