  Cycloaddition of a chiral nitrone to allylic motifs: an access to enantiopure sugar-based amino acids displaying a stable glycosidic bond and to 4(S)-4-hydroxy-l-ornithine

  摘要：

  A (-)-menthone-derived nitrone and various allyl O-, and S-glycosides reacted at 110 degrees C to afford the corresponding cycloadducts in good yields. For an N-acetylated allyl N-glycoside, an N-glycoside-based product was formed in poor yield with loss of the N-acetyl residue, while the major product 4 (60%), in which the sugar moiety was absent, arose from cleavage of the N-glycosidic bond, under the cyclo-addition conditions. The cycloadducts of the O-, and S-glycoside type were ring-opened and subjected to acidic and basic hydrolysis, for removing the chiral auxiliary. This resulted in glycosidic bond cleavage for O-glycosides and loss of material, while an S-glycoside amino acid was isolated in 78% yield, indicating a higher resistance of the S-glycosidic bond. N-O Bond cleavage and hydrolytic treatments applied to 4 afforded 4(S)-4-hydroxy-L-ornithine in high yield. Use of the nitrone derived from (+)-menthone should afford the enantiomer of 4, both precursors of 4-hydroxy arginine derivatives by guanidination. (C) 2011 Elsevier Ltd. All rights reserved.

  Stereoselective Synthesis of β-Glycosyl Thiols and Their Synthetic Applications

  摘要：

  A significantly fast reaction condition for the exclusive preparation beta-glycosyl thiol derivatives has been developed successfully. The reaction condition is one-step, fast, high yielding, highly stereoselective, and requires only benchtop chemicals. Further reaction of glycosyl thiol derivatives with Michael acceptors and alkylating agents furnished thioglycosides and (1,1)-thiolinked trehalose analogs.

  Primary allylic selenosulfates (seleno Bunte salts) and selenocyanates transfer the allylic selenide moiety to thiols giving primary allylic selenosulfides, which undergo rearrangement in the presence of PPh3 with the loss of selenium to give allylically rearranged allyl alkyl sulfides. This rearrangement may be conducted with prenyl-type selenosulfides to give isoprenyl alkyl sulfides. Alkyl secondary

  A series of β-D-glucopyranosyl derivates have been synthesized and evaluated in photooxidation reactions promoted by visible light and mediated by organic dyes under aerobic conditions. Among the different photocatalysts employed, tetra-O-acetyl riboflavin afforded chemoselectively the respective sulfoxides, without over-oxidation to sulfones, in good to excellent yields and short reaction times.

  An efficient one‐pot protocol for the direct preparation of thioglycosides starting from unprotected reducing sugars via S‐glycosyl isothiouronium salts is reported. In this one‐pot methodology, BF3 · OEt2 has been used as a general catalyst for both per‐O‐acetylation of sugars and conversion of sugar per‐O‐acetates into S‐glycosyl isothiouronium salts, which was allowed to react with alkylating agents

• Allylic Selenosulfide Rearrangement:  A Method for Chemical Ligation to Cysteine and Other Thiols
  作者：David Crich、Venkataramanan Krishnamurthy、Thomas K. Hutton

  日期：2006.3.1

  Alkylation of potassium selenosulfate with allylic halides gives Se-allyl seleno Bunte salts. On reaction with thiols at room temperature, these afford mixed dialkyl selenosulfides, which undergo 2,3-sigmatropic rearrangement with loss of selenium, either spontaneously or with assistance by triphenylphosphine, thereby providing mixed dialkyl sulfides and a new permanent chemical ligation method. The process is illustrated through the lipidation of cysteine-containing tripeptides and by the allylation of 1-thioglucose tetraacetate.
