Crich, David published the artcileDirect Stereocontrolled Synthesis of 3-Amino-3-deoxy-β-Mannopyranosides: Importance of the Nitrogen Protecting Group on Stereoselectivity, Safety of 1-(Phenylsulfinyl)piperidine, the publication is Journal of Organic Chemistry (2007), 72(14), 5183-5192, database is CAplus and MEDLINE.

The highly stereocontrolled synthesis of the 3-amino-3-deoxy-β-mannopyranosides is achieved by means of thioglycoside donors protected with a 4,6-O-benzylidene or alkylidene acetal and a benzylidene imine group. Among the various nitrogen protecting groups investigated only the Schiff’s base was found to give high β-selectivity. N-Phthalimido and N-acetamido protected donors were found to be highly α-selective, whereas 3-azido-3-deoxy glycosyl donors gave intermediate selectivity. The reasons for the protecting group dependency are discussed in terms of the change in the O2-C₂-C₃-N3 torsional interaction on conversion of the covalent glycosyl triflates to the transient oxa-carbenium ions.

Non-ATP competitive pyrimidine-based inhibitors of CaMKIIδ were identified. Computational studies were enlisted to predict the probable mode of binding. The results of the computational studies led to the design of ATP competitive inhibitors with optimized hinge interactions. Inhibitors of this class possessed improved enzyme and cellular activity compared to early leads.

Frihed, Tobias Gylling published the artcileInfluence of O6 in Mannosylations Using Benzylidene Protected Donors: Stereoelectronic or Conformational Effects?, Formula: C11H15NOS, the publication is Journal of Organic Chemistry (2013), 78(6), 2191-2205, database is CAplus and MEDLINE.

The stereoselective synthesis of β-mannosides and the underlying reaction mechanism have been thoroughly studied, and especially the benzylidene-protected mannosides have gained a lot of attention since the corresponding mannosyl triflates often give excellent selectivity. The hypothesis for the enhanced stereoselectivity has been that the benzylidene locks the mol. in a less reactive conformation with the O6 trans to the ring oxygen (O5), which would stabilize the formed α-triflate and subsequent give β-selectivity. In this work, the hypothesis is challenged by using the carbon analog (C7) of the benzylidene-protected mannosyl donor, which is investigated in terms of diastereoselectivity and reactivity and by low-temperature NMR. In terms of diastereoselectivity, the C-7-analog behaves similarly to the benzylidene-protected donor, but its low-temperature NMR reveals the formation of several reactive intermediate. One of the intermediates was found to be the β-oxosulfonium ion. The reactivity of the donor was found to be in between that of the “torsional” disarmed and an armed donor.

Crich, David published the artcileThe 3,4-O-Carbonate Protecting Group as a β-Directing Group in Rhamnopyranosylation in Both Homogeneous and Heterogeneous Glycosylations As Compared to the Chameleon-like 2,3-O-Carbonates, SDS of cas: 4972-31-0, the publication is Journal of Organic Chemistry (2003), 68(22), 8453-8458, database is CAplus and MEDLINE.

It is demonstrated that the β-selectivity observed in the insoluble silver salt mediated couplings of 2,3-O-carbonate-protected rhamnosyl bromides is uniquely due to the heterogeneous nature of the reaction. In homogeneous solution these same donors are α-selective, a fact that is attributed to the half-chair conformation of these substances which reduces the energy barrier to oxacarbenium ion formation. It is suggested that the 2,3-O-carbonate group be dubbed torsionally arming in the manno- and rhamnopyranose series. When the carbonate group is removed to the 3,4-O-position a β-selective system is formed, in both homogeneous and heterogeneous conditions, and it is demonstrated that this selectivity arises from the combination of the electron-withdrawing nature of the carbonate and its inability to take part in neighboring participation.

A series of 6-mono-, di-, and trifluoro analogs of S-Ph 2,3,4-tri-O-benzyl-D– or L-thiorhamnopyranoside has been synthesized and used as donors in glycosylation reactions, with activation by the 1-benzene-sulfinyl piperidine/triflic anhydride system. The stereochem. outcome of the glycosylation reactions was found to depend on the electron-withdrawing capability of the disarming substituent at the 6-position, i.e., on the number of fluorine atoms present. The results are explained with regard to the increased stability of the glycosyl triflates, shown to be intermediates in the reaction by low-temperature ¹H NMR experiments, with increased fluorine content.

Boehme, Horst published the artcileCleavage of aminals and of α-dialkylamino ethers by simple and mixed anhydrides, Related Products of piperidines, the publication is Justus Liebigs Annalen der Chemie (1965), 78-93, database is CAplus.

Cleavage of aminals R₂NCH₂NR₂ with (RSO₂)₂O, [(RO)₂P(O)]₂O and [(RO)₂P]₂O (Ia) affords an equimolar mixture of a dialkylmethyleneimmonium salt [R₂N: CH₂]⁺X^– of the corresponding acid, and its amide. With mixed anhydrides, the immonium salt of a stronger acid results together with an amide of the weaker one. α-Dialkylamino ethers react in the same manner giving rise to esters instead of amides. In the case of Ia the intermediate immonium salts rearrange by Michaelis-Arbuzov rearrangement into the esters of dialkylaminomethylphosphonic acids. Acetyl nitrate cleaves aminals in a different manner giving rise to a mixture of dialkyl nitramines and acetoxymethyldialkylamines. Consistently with the above scheme, mixed anhydrides are converted with MeOH or HCl to a mixture of a free stronger acid and an ester or chloride, resp., of the weaker one. All reactions were run under N and with a strict exclusion of air moisture. Into a solution of 10.2 g. (Me₂N)₂CH₂ (I) in Et₂O was added dropwise 17.4 g.

Synthesis of a pentasaccharide repeating unit corresponding to the cell wall O-antigen of Escherichia coli O59 has been achieved by orthogonal glycosylation and two iterative glycosylations in one pot. Synthesis of a β-D-mannosidic linkage present in the mol. has been successfully achieved with satisfactory yield by the activation of thioglycoside with a combination of 1-benzenesulfinyl piperidine (BSP) and triflic anhydride (Tf₂O). The α-D-glucosaminyl moiety was achieved in moderate yield from the α-D-mannosyl moiety by azidolysis of C-2 hydroxy group with inversion of configuration. TEMPO mediated selective oxidation of the primary hydroxyl group has been carried out at the late stage of the synthetic strategy.

In this article, we describe the synthesis of γ-lactones through the reaction of sulfoxonium ylides, aldehydes, and disubstituted ketenes [e.g., ylide precursor I.BF₄^– + benzaldehyde + isobutylphenylketene â†?II (60%, 83:17 dr)]. The one-pot sequential method provides access to γ-lactones from disubstituted ketenes, in moderate to excellent yields, and with good diastereoselectivity favoring the trans-diastereomer (dr up to 92:8). The reaction mechanism was investigated by performing labeling, crossover, and various control experiments The results of those experiments support the reaction mechanism involving betaine formation, reaction of the betaine with a ketene to form an enolate intermediate, [3,3]-sigmatropic rearrangement of an enolate intermediate, and finally, 5-exo-tet cyclization to afford the γ-lactone product.

This reaction enriches the research content of Selectfluor and provides a valuable vista for the convenient synthesis of sulfinamides.

Selectins are a class of cell adhesion mols. that play a critical role during the initial steps of inflammation. The N-terminal domain of P-selectin glycoprotein ligand-1 (PSGL-1) binds to all selectins, but with highest affinity to P-selectin. Recent evidence suggests that the blockade of P-selectin/PSGL-1 interactions provides a viable therapeutic option for the treatment of many inflammatory diseases. Herein, we report the total synthesis of threonine bearing sialyl Lewis^x (sLeX) linked to a Core-1-O-hexasaccharide 1, as a key glycan of the N-terminal domain of PSGL-1. A convergent synthesis using α-selective sialylation and a regioselective [4+2] glycosylation are the key features of this synthesis.
