  Total Synthesis of C-Glycosylangucycline, Urdamycinone B, Using an Unprotected Sugar

  摘要：

  The total synthesis of urdamycinone B (1), a prototypical member of the C-glycosylangucycline antibiotics, was achieved by a novel and effective strategy without any protecting group in the sugar moiety. The unprotected C-glycosyljuglone 6 was effectively synthesized by the aryl C-glycosidation of 1,5-naphthalenediol (16) with the totally unprotected D-olivose (8) and the subsequent regioselective photooxygenation of the resultant C-glycosylnaphthalenediol 17. On the other hand, the diene 7 was prepared from 3-methyl-2-cyclohexen-1-one (9) in a short step via the cross-coupling of the vinyl triflate 20 and vinylbutyltin (21) and the Wittig reaction of the aldehyde 24 and the phosphine 25. Finally, the regioselective Diels-Alder reaction of the unprotected C-glycosyljuglone 6 and the diene 7, followed by the regioselecitive introduction of the ketone function at the C1 position, led to the total synthesis of 1.

  Unusual stereoselectivity in sialic acid aldolase-catalyzed aldol condensations: synthesis of both enantiomers of high-carbon monosaccharides

  摘要：

  An inversion of stereoselectivity in aldol condensations catalyzed by sialic acid aldolase (from Escherichia coli, Shinko American Inc.) was observed when L-mannose, 6-deoxy-L-mannose, L-talose, 2-deoxy-L-glucose, 2-deoxy-L-rhamnose, N-acetyl-L-mannosamine, D-gulose, D-arabinose, and 2-azido-2-deoxy-L-mannose were used as acceptor substrates. In all substrates tested, except the last three, a complete inversion of stereoselectivity was observed; i.e., the C-nucleophile of pyruvate attacks the re face of the acceptor carbonyl instead of the si face as in the normal case for the enantiomeric substrates. Examination of the product distribution during the course of enzymatic reactions indicates that the stereoselectivity is thermodynamically controlled in nature; i.e., attack on the re face would take place if the resulting product would be more stable than the one from the si face attack. Both enantiomers of several high-carbon monosaccharides are now accessible via the aldolase reactions. A new practical procedure has also been developed for the preparation of the aldolase products where unreacted pyruvate (usually used in 7-fold excess to drive the reaction) is decomposed with pyruvate decarboxylase to simplify product isolation.

  Abstract The reduction of 2,6-dibromo-2,6-dideoxy- D -mannono- and 2,6-dibromo-2,6-dideoxy- D -glucono-1,4-lactone with sodium borohydride affords 2,6-dibromo-2,6-dideoxy- D -mannose and 2,6-dibromo-2,6-dideoxy- D -glucose, respectively, which may be isolated as their acetates. Similarly, 2-bromo-2,6-dideoxy- L- -glucono-1,4-lactone yields 2-bromo-2,6-dideoxy- L -glucose. Hydrogenolysis of 2,6-dibromo-2

  A practical synthetic strategy has been developed for producing uncommon sugars. This method employed kinetic enzymatic resolution of 1-(2-furyl)ethanol, and followed by NBS-mediated Achmatowicz rearrangement to construct α,β-unsaturated lactones. After further derivatization, five representative uncommon sugar units were successfully synthesized.

  The structure of UCH9, which is a novel antitumor agent, was determined by spectroscopic methods. UCH9 consists of an aglycone and five 2, 6-dideoxy sugars (three D-olivoses, one 4-O-methyl-D-olivose and one D-oliose). Four of the five sugars are sequentially connected through a β1→3 linkage (olivose-1→3-4-O-methyl-olivose-1→3-oliose-1→3-olivose). On the basis of the results of spectroscopic analysis, it was found that UCH9 belongs to the aureolic acid family of antibiotics. The structure of UCH9 is unique in that mono- and tetrasaccharide moieties, and a long hydrophobic side chain (sec-butyl group) are attached to the aglycone, while di- and trisaccharide moieties and a methyl or a hydrogen are attached in the case of the known aureolic acid analogs. It is known that aureolic acid analogs form a dimer in the presence of Mg2+. NMR, FAB-MS and atomic absorption analysis revealed that UCH9 isolated from Streptomyces also forms a dimer, containing one equivalent molar Mg2+

  UCH9的结构是一种新型抗肿瘤剂，通过光谱方法确定。UCH9由一个非糖部分和五种2,6-二脱氧糖组成（包括三个D-橄榄糖、一个4-O-甲基-D-橄榄糖和一个D-橄榄糖）。五种糖中有四种通过β1→3连接依次相连（橄榄糖-1→3-4-O-甲基-橄榄糖-1→3-橄榄糖-1→3-橄榄糖）。根据光谱分析的结果，发现UCH9属于金黄色酸类抗生素。UCH9的结构独特，因为它的非糖部分连接了单糖和四糖基团，以及一个长的疏水性侧链（叔丁基），而已知的金黄色酸类类似物则连接了二糖和三糖基团以及一个甲基或氢。已知金黄色酸类类似物在存在Mg2+的情况下会形成二聚体。NMR、FAB-MS和原子吸收分析显示，从放线菌中分离的UCH9也形成了一个含有一个当量摩尔的Mg2+的二聚体。
