  An efficient and highly stereoselective synthesis of nucleoside derivatives from furanoid 1,2-diols

  摘要：

  Reaction between suitably protected furanoid glycals 1b-4b, readily obtained from furanoid 1,2-diols (1a-4a), and different silylated pyrimidine bases, gave the corresponding 3',5'- and 3',5',6'-O-protected 2'-deoxy-2'-iodo-beta-D-xylo-pentofuranosyl 5-10 and beta-D-gluco-hexofuranosyl 11 nucleosides, respectively. Compound 5 has been transformed into its 2'-deoxy 12 and 2',3'-anhydro 14 derivatives. The high stereoselectivity of the reaction is discussed. (C) 1997 Elsevier Science Ltd.

• Inversion of secondary chiral alcohols in toluene with the tunable complex of R3NR′COOH

  The S(N)2 reaction of enantiomerically pure sulfonates with the tunable complex of R3N-R'COOH in toluene has been extensively studied. It was revealed that the molar ratio of the tertiary amines and carboxylic acids in the complex of R3NR'COOH is crucial for the S(N)2 reaction, and should be tuned for each sulfonate to give the best yield. Fifteen sulfonates 1 and 3-13 (Scheme 2) were prepared and transformed into 22 corresponding inverted esters 2 and 14-24 (Scheme 2) in good to high yields. (C) 2010 Elsevier Ltd. All rights reserved.
• Stereoselective Synthesis of 2'-Deoxy-.beta.-D-threo-pentofuranosyl Nucleosides by the NBS-Promoted Coupling Reaction of Thioglycosides with Silylated Heterocyclic Bases

  The NBS-promoted coupling reaction of phenyl 3,5-O-isopropylidene-2-deoxy-1-thio-alpha-D-threo-pentofuranoside (5e) with silylated pyrimidine bases was found to proceed in a highly stereoselective manner (alpha:beta = 1:24-0:1) to afford 2'-deoxy-beta-D-threo-pentofuranosyl pyrimidine nucleosides in satisfactory yields. The highly stereoselective outcome is thought to result from an in situ anomerization-type mechanism, in which intimate ionic intermediates would be in equilibrium and anomerize to the sterically preferable a form. A subsequent S(N)2 type attack to the intermediate will lead to the beta-nucleosides. By using this method, the synthesis of L-nucleosides, 1-(2-deoxy-beta-L-threo-pentofuranosyl)thymine and cytosine derivatives, was also demonstrated by starting from the L-enantiomer of the thioglycoside. On the other hand, the reaction with purine bases was accompanied by the production of undesirable N-7 regioisomers besides the desired N-9 products. The product distribution of the regioisomers was, however, proved to change with reaction time. For instance, a long reaction period allowed the thermodynamically stable N-9 isomers to be exclusively produced with moderate selectivity (alpha:beta = 1:2-1:4.8). The isolated yields of the 9-beta isomers after purification were acceptable for practical use.

  The coupling of the 3,5-O-isopropylidene derivative of phenyl 2-deoxy-1-thio-D-threo-pentofuranoside with silylated thymine in the presence of N-bromosuccinimide yielded 1-(2-deoxy-beta-D-threo-pentofuranosyl)thymine with highly anomeric selectivity.
