| titleOfInvention | Preparation method of ent-(14S)-3-methoxyl-17-morphinan |
| abstract | The invention discloses a preparation method of ent-(14S)-3-methoxyl-17-morphinan. The method comprises the following step of: enabling (+)-N-methyl-1-(4- methoxyl) benzyl-1,2,3,4,5,6,7,8-octahydro isoquinoline (I) to be subjected to cyclization reaction under the action of lewis acid, so as to produce the high-purity ent-(14S)-3-methoxyl-17-morphinan (D). The preparation method is simple in process, the prepared product is high in purity, and in comparison with the standard substance, the purity of the product is completely consistent with that of the standard substance. |
