合成路线1
该中间体在本合成路线中的序号：(III)Phenylsulfanyl glycoside (I) was coupled with serine derivative (II) in the presence of N-bromosuccinimide, iodine and tetrabutylammonium triflate yielding the serine glycoside (III). Reductive cleavage of the trichloroethoxy carbonyl group of (III) with Zn and HOAc afforded amine (IV), which was acylated with (R)-3-(tetradecanoyloxy)tetradecanoic acid (V) using DCC and HOBt. Hydrogenolysis of the benzyl ester (VI) over palladium black provided carboxylic acid (VII).
