合成路线1
该中间体在本合成路线中的序号：(III)Reaction of D-tartaric acid (I) with EtOH in the presence of an acid catalyst gives diethyl D-tartrate (II), which is treated with isobutyraldehyde and anhydrous CuSO4 in the presence of methanesulfonic acid yielding diethyl 2,3-O-isobutylidene-D-tartrate (III). The 1,3-dioxolane diester (III) was then reduced with LAH to afford (4R,5R)-4,5-bis(hydroxymethyl)-2-isopropyl-1,3-dioxolane (IV), which is treated with methanesulfonyl chloride in pyridine yielding (4R,5R)-4,5-bis(methylsulfonyloxymethyl)-2-isopropyl-1,3-dioxolane (V). The bis(methanesulfonate) (V) is reacted with NaN3 in DMF to give (4R,5R)-4,5-bis(azidomethyl)-2-isopropyl-1,3-dioxolane (VI), which is reduced with hydrogen in the presence of 10% Pd/C in EtOH to afford (4R,5R)-4,5-bis(aminomethyl)-2-isopropyl-1,3-dioxolane (VII). The diamine (VII) is reacted with an equimolar amount of in situ generated K2PtI4 to afford cis-diiodo[(4R,5R)-4,5-bis(aminomethyl)-2-isopropyl-1,3-dioxolane] platinum(II) (VIII), which is finally treated with malonic acid disilver salt in H2O to obtain (IX).
