摘要
The reduction of 2,3-epoxy alcohol, prepared from the Sharpless asymmetric epoxidation, with the system of Ph3P, iodine, iwhdazole, 2,6-lutidine and water in Et2O/CH3CN,gives a chiral secondary allylic alcohol in 94% yield and 92% e.e.. Using this reaction as the key step, we synthesized (-)-coniferyl alcohol derivative 1 steding from the geraniol through nine steps in an overall yield of 39%.
