  Syntheses of α-Fluoro-α,β-unsaturated Thioamides and Thiazolines from a Fluorophosphonodithioacetate

  摘要：

  A high-yielding synthesis of methyl fluoro(diethoxyphosphono)dithioacetate starting from its difluorinated analogue is reported. Fluorophosphonothioacetamides and -methylthiazolines, prepared from this new dithioester, have been successfully transformed into highly functionalized fluoroalkenes. Good stereoselectivity in favor of the E isomer was observed from the fluorophosphonomethylthiazolines. The potential of these new fluorinated olefinating reagents for the synthesis of modified peptides and glycosides is also disclosed.

  Addition of free radicals to the three dithioesters led to the detection of the ESR spectra of the spin adducts only with the last two compounds. Based on the reduction potentials of the three dithioacetates, this may be explained by capto-dative stabilization of the adducts. On the basis of DFT calculations, the temperature dependent variations of the spectral patterns exhibited by the radicals were attributed

  通过循环伏安法测量二乙氧基磷酰基二硫代乙酸乙酯（1），二乙氧基磷酰基氟二硫代乙酸甲酯（2）和二乙氧基磷酰基二氟二硫代乙酸甲酯（3）的氧化还原性质。在三个二硫代酸酯中添加自由基导致仅对最后两种化合物检测到自旋加合物的ESR光谱。基于三种二硫代乙酸酯的还原电位，这可以通过加合物的键合-稳定性加以解释。基于DFT计算，由自由基显示的光谱图案的温度依赖性变化归因于围绕Calpha-SMe键的受限旋转。

  A two-step, high-yielding synthesis of Delta(2)-thiazolines containing a difluoromethylphosphonate diester moiety has been devised using a building block approach. Racemic or chiral beta-amino alcohols and diols were coupled with methyl difluoro(diethoxyphosphono)dithioacetate to give predominantly the corresponding beta-hydroxythioamides, which were then cyclized to provide a series of novel substituted Delta(2)-thiazolines.

  Phosphonodiflourodithioacetate 2 demonstrates high reactivity towards dienes due to the presence of the two fluorine atoms. A hetero Diels-Alder reaction afforded the corresponding dihydrothiapyrans in 60-90% yields. These adducts can be submitted to a selective dihydroxylation and desulfanylation to produce phosphonodifluorothiaglycoside precursors. (C) 2002 Elsevier Science Ltd. All rights reserved.

  In this paper, we describe a short synthesis of N-(phosphonoacetyl)-L-aspartate (PALA) analogues. The mono- and difluorinated thioacetamide precursors were prepared in one step from methyl (diethoxyphosphono)di- and monofluoromethyldithioacetates 8 and 11 as starting materials. Antiproliferating properties on a L1210 strain and ATCase inhibition of these new compounds are disclosed. ThioPALA(FF) 5c showed a remarkable cytotoxic activity towards murine leukemia L1210, when used as tetraester. (c) 2005 Elsevier Ltd. All rights reserved.
