Methods based on a ring-contraction of cyclic αβ-epoxy-ketones to give α-hydroxy-acids are used for the preparation of some 8-methyl-trans-perhydroindanone derivatives of possible interest in connection with the synthesis of 9,10-seco-steroids. They include the unsaturated ketones (10) and (22), and the hydroxy-ketones (14), (21), (46), and (49).
Compounds of formula (I) ##STR1## as defined by the specification. The compounds are useful in the treatment or prevention of vitamin D dependent disorders, particularly psoriasis, basal cell carcinomas, disorders of keratinization and keratosis, leukemia, osteoporosis, hyperparathyroidism accompanying renal failure, transplant rejection and graft vs. host disease.
The novel compound 1α,26-dihydroxy-D-homo-vitamin D3 can be used for the treatment of vitamin D dependent disorders, such as psoriasis; leukemia; acne and seborrhoic dermatitis; osteoporosis; and hyperparathyroidism accompanying renal failure.
新型化合物 1α,26-二羟基-D-维生素 D3 可用于治疗维生素 D 依赖性疾病,如银屑病、白血病、痤疮和脂溢性皮炎、骨质疏松症以及伴随肾功能衰竭的甲状旁腺机能亢进症。
