Kumar, Chidambaram Ramesh published the artcileThe first total synthesis of cytopiloyne, an anti-diabetic, polyacetylenic glucoside, Name: 1-(Phenylsulfinyl)piperidine, the publication is Chemistry – A European Journal (2011), 17(31), 8696-8703, S8696/1-S8696/29, database is CAplus and MEDLINE.

The first total synthesis of cytopiloyne 1, a novel bioactive polyacetylenic glucoside isolated from the extract of Bidens pilosa, is described. The structure of cytopiloyne was determined to be 2-β-D-glucopyranosyloxy-1-hydroxytrideca-5,7,9,11-tetra-yne by using various spectroscopic methods, but the chirality of the poly-yne moiety was unknown. Herein, the convergent synthesis of two diastereomers of cytopiloyne by starting from com. available 4-(2-hydroxyethyl)-2,2-dimethyl-1,3-diozolane is described. The synthetic sequence involved two key steps: stereoselective glycosylation of the glucosyl trichloroacetimidate with 1-[(4-methoxybenzyl)oxy]hex-5-yn-2-ol to give the desired β-glycoside and the construction of the glucosyl tetra-yne skeleton by using a palladium/silver-catalyzed cross-coupling reaction to form the alkyne-alkyne bond, the first such use of this reaction. Comparison between the observed and published characterization data showed the 2R isomer to be the natural product cytopiloyne.

The effectiveness in terms of yield and stereoselectivity of (phenylsulfinyl)piperidine (BSP)/ trifluoromethanesulfonic anhydride (Tf₂O) and di-Ph sulfoxide (DPS)/ Tf₂O-mediated glycosidations of 2-azido-3-O-benzyl-4,6-O-benzylidene-2-deoxy-D-thiomannosides is described. Application of the BSP/Tf₂O activator led to productive condensations using p-methoxyphenyl 2-azido-3-O-benzyl-4,6-O-benzylidene-2-deoxy-D-thiomannoside as a donor, while the more powerful DPS/Tf₂O combination gave similar results using both p-methoxyphenyl and Ph 2-azido-3-O-benzyl-4,6-O-benzylidene-2-deoxy-D-thiomannosides.

Double duty: A phosphoric ester at the C2 position in glycosyl donors directs the glycosylation to occur selectively at the anomeric carbon atom with complete 1,2-trans selectivity. Since the phosphoric ester can be removed to give the hydroxy function, this group serves as a stereo-directing protecting group in oligosaccharide synthesis.

Son, Sang-Hyun published the artcileStereoselective tris-glycosylation to introduce β-(1→3)-branches into gentiotetraose for the concise synthesis of phytoalexin-elicitor heptaglucoside, Application of 1-(Phenylsulfinyl)piperidine, the publication is Organic & Biomolecular Chemistry (2008), 6(8), 1441-1449, database is CAplus and MEDLINE.

Dodecyl thioglycosides (3, 4, 5) were prepared by conventional transformation of d-glucose and used as new glycosyl donors for a short-step synthesis of phytoalexin elicitor heptaglucoside. A gentio-tetraoside derivative (6) having three hydroxyl groups was synthesized by NIS-TfOH promoted glycosylate in more than 90% yield followed by selective removal of temporary protective groups. Undesired formation of α-glycosides at the introduction of β-(1→3)-branches into gentio-oligosaccharides was found to be suppressed by use of a thiophilic reagent system, BSP (1-benzenesulfinyl piperidine)-Tf₂O, giving the heptaglucoside in only four glycosylation steps.

Total synthesis of (+)-TMC-151C by a highly convergent synthetic route, is reported. Characteristic features of the present synthesis include the construction of the C₁-C₅ and C9-C₁₃ units by vinylogous Mukaiyama aldol reactions and the use of a silicon-tethered diene for the stereoselective formation of the C₆-C₇ double bond by our recently developed E-selective ring-closing metathesis reaction to give an eight-membered ring. This synthetic strategy should provide efficient access to a range of related naturally occurring polyketides containing pent-2-ene-1,5-diol units.

Crich, David published the artcileIs Donor-Acceptor Hydrogen Bonding Necessary for 4,6-O-Benzylidene-directed β-Mannopyranosylation? Stereoselective Synthesis of β-C-Mannopyranosides and α-C-Glucopyranosides, Recommanded Product: 1-(Phenylsulfinyl)piperidine, the publication is Organic Letters (2008), 10(21), 4731-4734, database is CAplus and MEDLINE.

2,3-Di-O-benzyl-4,6-O-benzylidene-thiohexopyranosides, on activation with 1-benzenesulfinyl piperidine and triflic anhydride, react with allyl silanes and stannanes, and with silyl enolethers to give C-glycosides. In the mannose series the β-isomers are formed selectively whereas the glucose series provides the α-anomers. This selectivity pattern parallels that of O-glycoside formation and eliminates the need to consider donor-acceptor hydrogen bonding in the formation of the O-glycosides.
