合成路线1
该中间体在本合成路线中的序号：(IX)(iii) An intramolecular oxidative coupling of the thiols to form a 15-membered disulfide-containing ring: To complete the synthesis of FR901228, the beta-hydroxymercaptoheptenoic acid (VIII) was coupled to the 16-membered cyclic depsipeptide (IV) using the BOP reagent, followed by LiOH-mediated hydrolysis, resulting in the free acid product (IX). Cyclization of the hydroxy acid (IX) with TsOH, DEAD and PPh3 and oxidation of the bis(S-triphenylmethyl)lactone (X) with iodine in methanol solution yielded the depsipeptide FR901228.
