四氫噻吩衍生物 (S)-diphenyl(tetrahydrothiophen-2-yl)methanol (1) 的合成是以市售5-溴戊酸為起始物，經由五步的合成路徑而得。除此之外，我們將探討 (S)-(1) 於不對稱催化領域的應用，如：不對稱環氧化反應、不對稱烯丙基取代反應。在不對稱環氧化的應用上，最佳可以得到反式產物 (34) 92 % e.e；而不對稱烯丙基烷化卅醚化的應用上，仍有改善的空間。A novel chiral tetrahydrothiophene derivative (1) was obtained enantioselectively from commercially available 5-bromopentanoic acid through a 5- step synthetic route. We also demostrated the applications of this chiral ligand in asymmetric sulfur ylide epoxidation and organometallic asymmetric allylic substitution.
