  Synthesis and antimitotic activity of novel 2-methoxyestradiol analogs. Part III

  摘要：

  The syntheses and antimitotic activity of several novel analogs of 2-methoxyestradiol are described. Structural modifications include ring-D homologation, aromatization of the six-membered ring-D to a chrysine type molecule, and introduction of unsaturation in five-membered ring-D along with substitution of alkyl and ethynyl groups for the 17 beta-hydroxy function. of nine analogs synthesized, five have demonstrated superior antiproliferative activities compared to 2-methoxyestradiol.

  微波辅助立体选择性杂环化合成雌酮系列中的新型环 d-稠合芳基吡唑啉

  摘要：

  雌酮系列中新型环 d-稠合 2-吡唑啉的微波辅助合成可从甾体 α,β-烯酮和肼衍生物有效地进行。16-亚苄基雌酮 3-甲基醚与肼在乙酸中的闭环反应产生了两个 16,17-顺式稠合吡唑啉的 2:1 非对映异构体混合物，这与之前关于立体选择性和产物的文献数据相反结构体。然而，美雌醇衍生的不饱和酮与不同芳基肼在酸性乙醇中的环化反应以良好至极好的收率提供杂环产物，而与所用试剂的芳环上存在的取代基无关。MW 条件还允许与对硝基苯肼发生闭环反应，这在常规加热下是不利的。

• Steroids 49. Investigations on the dehydration of 17α-ethynl-17β- hydroxysteroids

  The acidic dehydration of 17alpha-ethynyl-17beta-hydroxysteroids (1-3) was investigated. On reaction with thionyl chloride, phosphorus oxychloride, and formic acid, the desired dehydration was accompanied by chlorination, Wagner-Meerwein rearrangement, and D-homoaromatic rearrangement. The structure of the product from the transformation of 17beta-hydroxypregn-20-yne derivative (3) on reaction with formic acid was misjudged. It was regarded as a pregn-16-en-20-yne (10) instead of the actually rearranged D-homoaromatic compound (11). As a consequence, physical data corresponding to this latter structure have been cited in the literature as those of pregn-16-en-20-yne derivative (10). This confusion prompted us to prepare compounds of both types (4, 9, 10, and 11), the characterization of which is here described.
