合成路线1
该中间体在本合成路线中的序号：(IV)Treatment of propargyl alcohol (I) with two equivalents of butyllithium in THF, followed by chlorotrimethylsilane, and then with methanol and a catalytic amount of distannoxane, gave 3-(trimethylsilyl)-2-propyn-1-ol (II). Partial reduction of acetylenic triple bond with sodium bis(2-methoxyethoxy)aluminum hydride afforded the expected (E)-olefin (III), which on treatment with methanesulfonyl chloride and triethylamine in dichloromethane provided mesylate (IV). Finally, alkylation of 1-deoxynojirimycin (V) with mesylate (IV) in the presence of triethylamine gave the title compound.
