    摘要:
    研究了环氧化,次溴酸的添加以及3-甲氧基-13alpha-estra-1,3,5(10),16-丁烯1与乙硼烷,儿茶酚硼烷和9-BBN的硼氢化反应,以确定其立体化学结果并合成新的13alpha-estra-1,3,5(10)-三烯用于生物学和构象研究。已经表明,空间上需要的试剂9-BBN参与了优选的β攻击(53%的16betaOH 10、34%的17betaOH 8、13%的16alphaOH 11)。该立体化学结果与另一个顺式加成反应的结果,即最近描述的1的OsO4二羟基化[Steroids 68(2003)113]一致。使用较小的试剂,例如B2H6,儿茶酚硼烷或单过氧邻苯二甲酸镁,观察到的立体选择性降低,而β攻击仅略有过量。次溴酸的离子反式加成反应产生了两种具有16beta,17alpha(4,76%)和16alpha,17beta构型(5,24%)的17-溴16-醇,通过16,17a

    The invention describes new compounds as pharmaceutical active ingredients, which have in vitro a higher affinity to estrogen receptor preparations from rat prostates than to estrogen receptor preparations from rat uteri and in vivo a preferential action on bone rather than the uterus, their production, their therapeutic use and pharmaceutical dispensing forms that contain the new compounds. The new compounds are 16α- and 16β-hydroxy-estra-1,3,5(10)-estratrienes, which carry additional substituents on the steroid skeleton and can have one or more additional double bonds in the B-, C- and/or D-rings.

  • Conformational Design for 13α-Steroids
    作者:Bruno Schönecker、Corinna Lange、Manuela Kötteritzsch、Wolfgang Günther、Jennie Weston、Ernst Anders、Helmar Görls
    DOI:10.1021/jo000108x
    日期:2000.9.1
    The diastereomeric 16-bromo- and 16-azido-17-alcohols 5-8, 11, 12, 16, and 17 and 17-ketones 3, 4, 9, and 10 of the 13 alpha-estra-1,3,5(10)-triene series were synthesized as precursors for biologically active compounds and chiral Ligands for metal complexation. Conformational investigations of these and some other compounds via X-ray analysis and H-1 NMR spectroscopy show the existence of compounds with the classical steroid conformation (ring C chair, restricted conformation of ring D) and such with an atypical ring C twist-boat and a flexible ring D conformation. It could be shown that 17 beta-substituents or flattening of the D-ring are responsible for the twist-boat conformation, whereas compounds containing a 17 alpha-substituent or 17 keto group possess the classical conformation. By varying the substituents, compounds with either of these conformations can be intentionally synthesized. MO calculations confirmed the relative stability of the twist-boat conformation.
  • Synthesis and conformation of four 16,17-diols in the 3-methoxy-13α-estra-1,3,5(10)-triene series
    作者:Sigfrid Schwarz、Bruno Schönecker、Kai Fritsche、Andreas Poser、Corinna Lange、Wolfgang Günther、Stephan Göttke、Helmar Görls、Siegfried Bäsler
    DOI:10.1016/s0039-128x(02)00175-7
    日期:2003.2
    All four diasteromeric 16,17-diols in the 3-methoxy-13alpha-estra-1,3,5(10)-triene series have been synthesized. The trans-diols 1 and 2 can be obtained by hydroborating the 17-enol acetate 6 (61%, ratio 27:73, preferred alpha attack). OsO4 dihydroxylation of the olefin 7 ;yielded the cis-diols 3 and 4 (ratio 13:87). The dihydroxylation proceeds with preference for beta attack caused b a C-ring twist-boat form of 7. The conformations of the diols 2 and 4, the 17-benzyl-17-hydroxy compounds 9 and 10 (obtained by Grignard reaction), and the 16alpha-bromo-17beta-hydroxy compound 8 were determined by X-ray analysis and by H-1 NMR spectroscopy in solution. Some compounds, in spite of a 17beta-hydroxy group, had a conformation with a ring C chair form (4, 8, 9) caused by intermolecular interaction in the solid state. The rest of the compounds studied here (2, 10) possessed a conformation with a ring C twist-boat form, which has been also found for all 1beta-substituted compounds in solution. The preferred conformation of the D-ring with 17beta-substituents seems to be the 16beta-envelope form or near this form, but the existence of the 16beta-envelope form (inversion of the ring D) for some compounds showed great variance in the conformation of ring D, which is substituent dependent.
