合成路线1

该中间体在本合成路线中的序号：(XI)

The selective hydrolysis of clarithromycin (I) with aqueous HCl, followed by acylation with acetic anhydride gives the monoacetylated descladinosyl compound (XI), which by reaction with trichloromethyl chloroformate (TCF) yields the cyclic carbonate (XII). The reaction of (XII) with 1,1,3,3-tetramethylguanidine (TMG) affords intermediate (XIII), which is selecti-ely acylated with 2-(2-pyridyl)acetic acid (X) and WSC giving the 3-O-acylated compound (XIV). The activation of (XIV) with CDI affords the 12-O-imidazolylcarbonyl derivative (XV), which is cyclized with ethylenediamine (IV) providing the carbamate (XVI). The alkylation of the primary amine of (XVI) by reductocondensation with pyridine-3-carbaldehyde (VI) and NaBH(OAc)3 gives the secondary amine (XVII).
