  syntheses of a series of 4-, 7-, 8- and 9-deoxygenated 2,3-difluoro-N-acetylneuraminic acid derivatives as potential mechanism-based inhibitors of sialidases. The syntheses commenced utilising an enzyme-catalysed aldolase reaction between N-acetyl mannosamine and β-fluoropyruvic acid to give 3-fluoro-N-acetyl-neuraminic acid. This common intermediate was then used in selective protection protocols and Barton-McCombie

  在这里，我们描述了一系列的4-，7-，8-和9-脱氧的2,3-二氟-N-乙酰神经氨酸衍生物作为唾液酸酶的潜在机理抑制剂的成功合成。利用N-乙酰甘露糖胺和β-氟丙酮酸之间的酶催化醛缩酶反应开始合成，得到3-氟-N-乙酰神经氨酸。然后将这种常见的中间体用于选择性保护方案和Barton-McCombie脱氧反应中，以生成一整套脱氧的3-氟-N-乙酰神经氨酸衍生物。最后，利用（二乙基氨基）三氟化硫（DAST）的氟化步骤成功地生成了每种目标二氟化物。

  Methods for promoting plant growth based on novel photosafening treatment regimes with glycopyranosides including glycopyranosylglycopyranosides, and aryl-a-D-glycopyranosides, and more specifically, with one or more compounds comprising terminal mannosyl-triose, optionally in the presence of light enhanced by one or more light reflecting and/or refracting members such as silicon-based substrates. Furthermore, chemical synthesis processes for the above compounds are disclosed for general application to plants. Silicate microbeads of the like are distributed over the ground or substrate in which roots of a plant are supported and planted, beneath and around a plant in a manner that light is refracted or reflected toward the phylloplane.
