  A simple procedure is reported for the stereoselective debromination of vic-dibromides with nickel boride at ambient temperature. Debromination with concomitant reduction of vic-dibromides to give dihydro products in a one-pot reaction is also reported. α,β-Dibromoketones can also be converted to their corresponding alcohols.Key words: debromination, vic-dibromides, stereoselective, reduction, E-alkenes.

• Design, synthesis and biological evaluation of bis(hydroxyphenyl) azoles as potent and selective non-steroidal inhibitors of 17β-hydroxysteroid dehydrogenase type 1 (17β-HSD1) for the treatment of estrogen-dependent diseases

  The combination of a ligand- and a structure-based drug design approach led to the identification of bis(hydroxyphenyl) azoles as potential inhibitors of 17beta-HSD1. Different azoles and hydroxy substitution patterns were investigated. The compounds were evaluated for activity and selectivity with regard to 17beta-HSD2, ERalpha and ERbeta. The most potent compound is 3-[5-(4-hydroxyphenyl)-1,3-oxazol-2-yl]phenol

  17beta-羟基类固醇脱氢酶1（17beta-HSD1）催化将活性较弱的雌酮（E1）还原为最有效的雌激素17beta-雌二醇（E2）。E2通过激活雌激素受体（ER）刺激激素依赖性疾病的生长。17beta-HSD1通常在乳腺癌细胞中过表达。因此，它是治疗乳腺肿瘤的有吸引力的靶标。配体和基于结构的药物设计方法的结合导致了对双（羟苯基）唑类化合物作为17β-HSD1潜在抑制剂的鉴定。研究了不同的唑和羟基取代方式。评估了化合物相对于17beta-HSD2，ERalpha和ERbeta的活性和选择性。最有效的化合物是3- [5-（4-羟基苯基）-1,3-恶唑-2-基]苯酚（18，IC（50）= 0.31 microM），

  Mono-O,O- and mono-S,S-ketals of 1,3-diphenylpropane-1,3-diones react with hydroxylamine hydrochloride and O-methylhydroxylamine hydrochloride affording mixtures of (E/Z) isomers which are hard to separate or an even unseparable. Isomerically pure oximes and O-methyloximes, however, are obtained either from 2-lithiated 1,3-dithianes and alpha-halogeno-oximes and alpha-halogeno-oxime ethers, resp., or from lithiated oxime ethers and dithienium salts. Reduction, acetylation, hydrolysis of the ketal increment, and oximation afford 3-amino-oximes which are precursors of 1,3-diphenylpropane-1,3-diamines.
