| titleOfInvention | 3-benzyloxy-tetrahydropyran, preparation method thereof and preparation method of tetrahydropyran-3-cyclic alcohol with single configuration |
| abstract | The invention relates to 3-benzyloxy-tetrahydropyran, a preparation method thereof and a preparation method of tetrahydropyran-3-cyclic alcohol with a single configuration, belonging to the technical field of medicines. The 3-benzyloxy-tetrahydropyran has a structure shown as a formula I or a formula II. The 3-benzyloxy-tetrahydropyran is generated by intramolecular etherification and one-step ring closure reaction of single-configuration 2-benzyloxy-pentane-1, 5-diol through anhydride catalysis, can be used for preparing single-configuration tetrahydropyran-3-cyclic alcohol, and has the advantages of simple preparation method, low cost and suitability for large-scale production. |
