Sh. Kang et Sb. Lee, A STEREOCONTROLLED SYNTHESIS OF SYN-2,5-DISUBSTITUTED TETRAHYDROFURANAND DIHYDROFURAN, Tetrahedron letters, 34(47), 1993, pp. 7579-7582
Iodoetherification of triethylsilyl ethers of trans-4-(3'-furanyl)-3-b
utenols has stereoselectively induced syn-2,5-disubstituted tetrahydro
furans 5s-10s, of which 5s has been readily converted into the corresp
onding dihydrofuran 21 and tetrahydrofuroate 22.
