  Incorporation of the bioactive moiety of leinamycin into thymidine

  摘要：

  A simple synthesis of 1,2-dithiolan-3-ones from alpha,beta-unsaturated thiophenyl esters has been elaborated. With the aim of introducing the biologically active 1,2-dithiolan-3-one-1-oxide moiety of leinamycin into a nucleoside, the method was successfully applied to thymidine-5'-aldehyde.

  Meyer-Schuster Rearrangement of .gamma.-Sulfur-Substituted Propargyl Alcohols: A Convenient Synthesis of .alpha.,.beta.-Unsaturated Thioesters

  摘要：

  gamma-Sulfur-substituted propargyl alcohols 1a-e and 1ij reacted with polyphosphoric acid trimethylsilyl ester (PPSE) to give the alpha,beta-unsaturated thioesters 3a-e and 3ij in good yields. However, the reactions of 3,3-dibutyl-1 -(phenylthio)propargyl alcohol (1k) and 1-(phenylthio)ethynyl- 1-cyclo alkanols 1l-n with PPSE gave the enyne sulfides 2k-n exclusively.

  of generating ketene intermediates via Ru-catalyzed intramolecular oxidation of terminal alkynes is applied to propargyl sulfoxides. The reaction undergoes interesting further rearrangement upon the ketene generation to afford α,β-unsaturated thioesters in good to excellent yields in the reported cases.

  我们以前开发的通过Ru催化的末端炔烃分子内氧化生成烯酮中间体的策略被应用于炔丙基亚砜。在所报道的情况下，该反应在产生烯酮时经历了令人感兴趣的进一步重排，从而以良好或优异的产率提供了α，β-不饱和硫代酯。

  日期：——

  A conjugate reduction of α,β-unsaturated thioesters catalyzed by copper hydride using PMHS as stoichiometric reductant has been developed. 1,2-Bis(diphenylphosphino)benzene (BDP) was the most effective ligand for this reduction. Saturated thioesters could be produced in excellent yields when the substituent on the thiol is not sterically-demanding. This protocol was applied to induce the reductive aldol cyclization of keto-enethioates, which could offer β-hydroxythioesters in moderate to good yields.

  已开发出一种由铜氢化物催化、使用PMHS作为化学计量还原剂的α,β-不饱和硫酯的共轭还原反应。1,2-双(二苯膦基)苯（BDP）是该还原反应最有效的配体。当硫醇上的取代基空间要求不高时，可以高产率地生成饱和硫酯。该方案被应用于诱导酮烯硫酯的还原性醛醇环化反应，从而在中等至良好产率下获得β-羟基硫酯。

  A simple synthesis of 1,2-dithiolan-3-ones from alpha,beta-unsaturated thiophenyl esters is reported. Introduction of the biologically active 1,2-dithiolan-3-one-1-oxide moiety of leinamycin into aldehydo-D-arabinose 11, the uridine derivative 16, and the deoxythymidine 21 was established. An extended bioactive part of leinamycin carrying a carbon-carbon triple bond was also synthesized. All of these analogues of leinamycin showed cytotoxic activity against HeLa3 tumor cells. Interestingly, the lipophilic, silyl group-containing derivatives proved to be more active than the hydrophilic counterparts.
