合成路线1
该中间体在本合成路线中的序号：(VI)Addition of tributyltin hydride to the triple bond of propargyl alcohol (I) in the presence of AIBN provided a mixture of (Z)-(II) and (E)-3-(tributylstannyl)-2-propen-1-ol (III), which were separated by column chromatography. The desired (E)-allyl alcohol (III) was further converted to the corresponding chloride (IV) by treatment with PPh3 in refluxing CCl4. Alkylation of the nortropane derivative (V) with chloride (IV) in the presence of celite-supported KF furnished the N-(tributylstannyl)propenyl nortropane (VI). The target iodinated compound was then prepared by treatment of (VI) with N-iodosuccinimide.
