  5-OP-RU立体化学对其稳定性和MAIT-MR1轴的影响

  摘要：

  位置、位置、位置：合成了 5-OP-RU 的所有立体异构体，以阐明其立体化学对依赖于 MR1 的 MAIT 细胞活化的影响。在立体异构体中，只有 4'-OH 差向异构体表现出强大的 MAIT 细胞活性，因此表明 2'-OH 和 3'-OH 基团的构型可能对激动活性很重要。

  Efficient syntheses of 1-bromodeoxy-, 1-azidodeoxy- and 1-aminodeoxypentitols from unprotected d-pentono-1,4-lactones

  摘要：

  The reduction of unprotected 5-bromo-5-deoxy-D-ribono, D-arabinono and D-xylono-1,4-lactones was achieved with NaBH4 in water-EtOH. The corresponding 1-bromo-1-deoxypentitols were isolated after acetylation in good overall yields (60-90%). 1-Azido-1-deoxypentitols were obtained quantitatively either by nucleophilic substitution by azide ion and deacetylation of the corresponding monobromopentitols or by reduction of the corresponding 5-azido-5-deoxy-D-pentono-1,4-lactones. The reduction of the monoazidopentitols by catalytic hydrogen transfer gave the monoaminopentitol analogues in quantitative yield.

• .alpha.-Amino aldehyde equivalents as substrates for rabbit muscle aldolase: synthesis of 1,4-dideoxy-D-arabinitol and 2(R),5(R)-bis(hydroxymethyl)-3(R),4(R)-dihydroxypyrrolidine

  日期：1991.6

  This work examined the application of rabbit muscle aldolase (RAMA) to stereospecific carbon-carbon bond formation in the preparation of carbohydrates containing amino groups. Several alpha-amino aldehyde equivalents were evaluated as substrates for RAMA and for their synthetic utility in transformations following the aldol reaction. This methodology is illustrated by the syntheses of the pyrrolidine alkaloids 1,4-dideoxy-D-arabinitol and 2(R),5(R)-bis(hydroxymethyl)-3(R), 4(R)-dihydroxypyrrolidine. The kinetic resolution of racemic aldehydes by RAMA and mild methods for transforming the amino equivalents into the desired amines are discussed briefly.

  Location, location, location: All the stereoisomers of 5‐OP‐RU were synthesized to elucidate the effects of its stereochemistry on MR1‐dependent MAIT cell activation. Of the stereoisomers, only the 4’‐OH epimer demonstrated potent MAIT cell activity, thus indicating that the configuration of the 2’‐OH and 3’‐OH group could be important for agonistic activity.
