Iodoetherification of triethylsilyl ethers of trans-4-(3′-furanyl)-3-butenols has stereoselectively induced syn-2,5-disubstituted tetrahydrofurans 5s-10s, of which 5s has been readily converted into the corresponding dihydrofuran 21 and tetrahydrofuroate 22.
反式-4-(3'-呋喃基)-3-丁烯醇的三乙基甲硅烷基醚的碘醚化具有立体选择性诱导的顺-2,5-二取代的四氢呋喃5s-10s,其中5s易于转化为相应的二氢呋喃21和四氢呋喃酸酯22。
