Novel intermediate compounds for synthesis of vitamin d derivatives |
| abstract |
FIELD: organic chemistry, chemical technology, vitamins. n SUBSTANCE: invention relates to novel intermediate compounds used for synthesis of derivatives of vitamin D and represented by the formula (I): wherein Y 1 represents hydrogen atom or tert.-butyldimethylsilyl group; Y 2 represents tert.-butyldimethylsilyl group; Y 3 represents hydrogen atom or tetrahydro-2-pyranyl group wherein Y 3 O-group is in R-configuration; R 1 and R 2 are bound and form methylene group. Except for, invention relates to novel compounds represented by the formula (II): wherein Y 2 represents tert.-butyldimethylsilyl group; Y 3 represents hydrogen atom or tetrahydro-2-pyranyl group and Y 3 O-group is in R-configuration. These compounds are used as intermediate substances for synthesis of compounds of the formula (I). n EFFECT: valuable properties of intermediate compounds. n 8 cl, 1 dwg, 8 ex |
