  First synthesis of a pentadeuterated 3′-hydroxystanozolol—an internal standard in doping analysis

  摘要：

  The first synthesis of 16,16,20,20,20-pentadeuterio-3'-hydroxystanozolol (8) in 26% yield over nine steps is described using moderately priced starting materials and economic amounts of reagents. Compound 8 can be used as an internal standard in screening procedures for anabolic steroids as well as for the quantification of stanozolol metabolites via mass spectrometric techniques, such as LC-MS or gas chromatography-mass spectrometry (GC-MS).

  新型葡萄糖6-磷酸脱氢酶类固醇抑制剂

  摘要：

  类固醇DHEA 1的新型衍生物设计，合成并测试了一种已知的G6PD非竞争性抑制剂G6PD抑制这种脱氢酶的能力。鉴定了几种在酶测定中具有约10倍改进的效力的化合物，并且这种改进的活性转化为细胞测定中的功效。用于类固醇抑制G6PD的SAR已得到实质性发展。3β-醇可用3β-H键供体代替，例如磺酰胺，磺酰胺，尿素和氨基甲酸酯。如果存在C-20酮，可以通过用孕烷核替换雄烷核来实现更高的效能。对于pregnan-20-ones，掺入21-羟基通常是有益的。新化合物通常具有良好的理化性质和令人满意的体外DMPK参数。

  In order to obtain the more precise knowledge on the nature of the dimethyl-tert-butylsilyloxy linkage, several steroid silyl ethers were prepared. The rate of acid-catalyzed hydrolysis was determined with the typical steroid derivatives. Convenient syntheses of 3β-hydroxy-4-androsten-17-one have also been described.

  A practical and broadly applicable catalytic method for the synthesis of (E)-alkenylborons is presented. Reactions are promoted by [Pd(Cl)(η3-C3H5)]2 and proceed by the dehydroboration of cyclic borates. Through the use of epoxides and readily available di-B(pin)-methane (pin = pinacolato), a range of allylic alcohol-containing alkenyl boronates, including those that contain a tertiary alcohol, may

  Abstract Two strategies have been explored for the synthesis of steroidal 20,16-γ-carbolactones from the corresponding 17-ketoandrostane. A highly efficient, stereospecific protocol has been developed for the β-oriented cis-γ-lactone, based on a Michael addition of cyanide to a conjugated ketone. A different approach, involving prior attachment of a 3-carbon side chain on C-17 of a 17-oxo-16β-acetoxy-androstane

  日期：2021.8.20

  1,2,3-Triazine 1-oxides are formed by nitrosyl addition from tert-butyl nitrite to the vinylogous position of vinyl diazo compounds. This transformation, which is a formal intermolecular [5 + 1] cycloaddition, occurs under mild conditions, with high functional group tolerance and regioselectivity, and can be employed for late-stage functionalization. Upon heating at refluxing chlorobenzene temperature

  1,2,3-三嗪 1-氧化物是通过亚硝酸叔丁酯与乙烯基重氮化合物的邻位位置的亚硝酰基加成而形成的。这种转化是正式的分子间 [5 + 1] 环加成，在温和的条件下发生，具有高官能团耐受性和区域选择性，可用于后期功能化。在回流的氯苯温度下加热时，这些三嗪-N-氧化物经历二氮挤压以非常高的产率形成异恶唑。
