SYNTHESIS OF OXYGEN-SUBSTITUTED BENZOCYCLOHEPTENES, USED AS VALUABLE INTERMEDIATE PRODUCTS FOR PRODUCING TISSUE-SELECTIVE OESTROGENS |
| 摘要 |
The invention relates to intermediate products and a novel method for producing benzocycloheptene C. The inventive method for producing the novel intermediate products of said compound is based on cost-effective starting materials, produces the intermediate stages with high yields and a high purity, without recourse to chromatographic purification steps and allows production on a large scale.
