  Baker's yeast mediated stereoselective biotransformation of 1-acetoxy-3-aryloxypropan-2-ones

  摘要：

  A series of 1-acetoxy-3-aryloxypropan-2-ones la-m were synthesized and subjected to biotransformation by baker's yeast yielding optically active monoacetates 5 or ent-5 and/or diols 4 of moderate to excellent enantiomeric purity. The dependence of the reduction/hydrolysis ratio and stereoselectivity on the size and substitution pattern of the aromatic moiety in the substrate is also discussed. (C) 1998 Elsevier Science Ltd.

• Regioselective acetylation of carbohydrates and diols catalyzed by tetramethyl-ammonium hydroxide in water

  A novel method for an efficient regioselective acetylation of carbohydrates and diols in aqueous solution is described. Treatment of substrates with 1-acetylimidazole, and tetramethyl-ammonium hydroxide (TMAH) in water under mild conditions gave highly regioselective acetylation for primary hydroxyl groups. This discovery provides an eco-friendly way for selective acetylation of non-protected glycosides

  描述了一种用于在水溶液中有效地对碳水化合物和二醇进行区域选择性乙酰化的新方法。在温和的条件下，在水中用1-乙酰基咪唑和氢氧化四甲基铵（TMAH）处理底物，可得到伯羟基的高度区域选择性乙酰化。该发现为水中非保护的糖苷和二醇的选择性乙酰化提供了一种环保的方法，避免了使用有毒有机溶剂和避免对仲羟基进行预保护的必要性。

  Epoxides can be cleaved in a regio- and stereoselective manner under neutral conditions with alcohols and acetic acid in the presence of catalytic amounts of decatungstocerate(IV) ion, ([CeW10O36]8−), affording the corresponding β-alkoxy and β-acetoxy alcohols in high yields. In water, ring opening of epoxides occurs with this catalyst to produce the corresponding diols in good yields.

  可以在中性条件下用醇和乙酸在催化量的decatungstocerate（IV）离子（[CeW 10 O 36 ] 8-）存在下，以区域和立体选择性的方式裂解环氧化合物，得到相应的β-烷氧基和β-乙酰氧基醇收率高。在水中，该催化剂会发生环氧化物的开环反应，从而以高收率生产出相应的二醇。

  Regioselective glycosylation of rac-guaifenesin (1A) with various glycosyl donors viz., β-d -glucosepentaacetate (2), pyridyl 2,3,4,6-O-tetra-O-benzyl-1-thio-β-d-galactopyranoside (9), 1-O-acetyl-2,3,5-tri-O-benzoyl-α/β-d-ribo- (13) and xylofuranoside (17) is reported. Glycosyl donors 2, 13 and 17 bearing ester protecting groups is reported to exhibit high regioselectivity to form the corresponding diastereomeric mixture of 1-O-glycosylated guaifenesin derivatives 3A, 14A and 18A, respectively; formation of diglycosylated derivatives 5A, 15A and 19A is not observed. While no such selectivity is observed when the donor 9 bearing ether protecting groups is used in the coupling reaction with 1A, resulting in the formation of digalactosylated derivatives 10A. That the regioselectivity is not dependent upon substituents present on the aromatic ring is shown by coupling 1B with 2 to isolate 1-O-glycosylated derivative 3B; formation of diglycosylated derivative 5B was not observed. Applicability of this finding is shown by preparation of enantiopure guaifenesin [(R)-1 (98% ee) and (S)-1 (98% ee)] by separation of their corresponding diastereomers (R)-3 and (S)- 3, respectively.

  本文报道了消旋的愈创甘油醚（1A）与各种糖供体，即β-D-葡萄糖五乙酸酯（2）、吡啶基2,3,4,6-O-四苄基-1-硫代-β-D-半乳糖吡喃糖苷（9）、1-O-乙酰基-2,3,5-三-O-苯甲酰基-α/β-D-核糖-（13）和木糖呋喃糖苷（17）的区域选择性糖基化反应。具有酯保护基的糖供体2、13和17被报道表现出高度的区域选择性，分别形成相应的1-O-糖基化愈创甘油醚衍生物3A、14A和18A的非对映异构体混合物；未观察到形成二糖基化衍生物5A、15A和19A。然而，当使用具有醚保护基的供体9进行与1A的偶联反应时，未观察到这种选择性，导致形成了二半乳糖基化衍生物10A。通过将1B与2偶联并分离出1-O-糖基化衍生物3B，表明区域选择性不依赖于芳环上的取代基；未观察到形成二糖基化衍生物5B。这一发现的适用性通过分离其相应的非对映异构体（R）-3和（S）-3，分别制备了具有高对映体纯度的愈创甘油醚[(R)-1（98% ee）和(S)-1（98% ee）]。
