  Novel methods for the reduction of α,β-epoxy ketones, α,β-epoxy esters (glycidic esters), and their congeners to β-hydroxy carbonyl compounds (aldols) by the use of organoselenium reagents are described. The reagents, a sodium phenylseleno(triethyl)borate complex Na[PhSeB(OEt)3] easily prepared by reduction of (PhSe)2 with NaBH4 in EtOH and benzeneselenol (PhSeH) generated in situ from the borate complex

  描述了通过使用有机硒试剂将α，β-环氧酮，α，β-环氧酯（缩水甘油酯）及其同类物还原为β-羟基羰基化合物（醛醇）的新方法。通过在EtOH中用NaBH 4还原（PhSe）2和原位生成的苯硒酚（PhSeH），可以轻松制备苯基硒基（三乙基）硼酸钠复合物Na [PhSeB（OEt）3 ]通过添加乙酸从硼酸盐配合物中得到的氯已被证明可作为这些转化的极好的还原剂。有机硒介导的α，β-环氧羰基化合物在α-碳上区域特异性还原，从而以优异的收率生产出多种环状（分子内）醇醛和非环状（分子间）醇醛。定量机理研究表明，与常见的电子转移还原剂相比，有机硒介导的还原通过α取代过程进行。

• Microbial hydroxylation of steroids. Part 12. Hydroxylation of testosterone and related steroids by <i>Gnomonia</i><i>fructicola</i> ATCC 11430

  The fungus Gnomoniafructicola ATCC 11430 hydroxylates testosterone at C-2β in 40–60% yield. The enzyme involved has been shown to be an inducible CO sensitive, cyanide insensitive oxygenase, with a requirement for theΔ⁴-3-ketosteroid substrate functionality. The use of 2α- and 2β-deuterium labelled substrates has shown that hydrogen loss from C-2 during 2β hydroxylation is isotope dependent and non-stereospecific. This is interpreted in terms of a Δ^2,4-dienolic enzyme-bound intermediate form of the substrate. Keywords: Gnomoniafructicola, hydroxylation, steroids, testosterone.

  真菌Gnomoniafructicola ATCC 11430以40-60%的产率在C-2β处对睾酮进行羟基化。所涉及的酶已被证明是一种可诱导的CO敏感、氰化物不敏感的氧化酶，需要Δ4-3-酮类固醇底物的功能性。使用2α-和2β-氘标记底物表明，在2β羟基化过程中，C-2处的氢损失是同位素依赖的，且不具有立体特异性。这被解释为底物的Δ2,4-二烯醇酶结合中间体形式。关键词：Gnomoniafructicola、羟基化、类固醇、睾酮。
