Lyu, Zhigang published the artcileSteric-free bioorthogonal labeling of acetylation substrates based on a fluorine-thiol displacement reaction, Recommanded Product: 2,4,6-Trimethoxybenzenethiol, the publication is Journal of the American Chemical Society (2021), 143(3), 1341-1347, database is CAplus and MEDLINE.

We have developed a novel bioorthogonal reaction that can selectively displace fluorine substitutions alpha to amide bonds. This fluorine-thiol displacement reaction (FTDR) allows for fluorinated cofactors or precursors to be utilized as chem. reporters, hijacking acetyltransferase-mediated acetylation both in vitro and in live cells, which cannot be achieved with azide- or alkyne-based chem. reporters. The fluoroacetamide labels can be further converted to biotin or fluorophore tags using FTDR, enabling the general detection and imaging of acetyl substrates. This strategy may lead to a steric-free labeling platform for substrate proteins, expanding our chem. toolbox for functional annotation of post-translational modifications in a systematic manner.

Pd(II)-catalyzed C-H functionalization of nondirected arenes has been realized using an inexpensive and easily accessible type of bidentate S,O-ligand. The catalytic system shows high efficiency in the C-H olefination reaction of electron-rich and electron-poor arenes. This methodol. is operationally simple, scalable, and can be used in late-stage functionalization of complex mols. The broad applicability of this catalyst has been showcased in other transformations such as Pd(II)-catalyzed C-H acetoxylation and allylation reactions.

In the presence of Pd(OAc)₂ and tri(2-furyl)phosphine in toluene/THF, arylzinc reagents derived from aryl iodides and an alkenylzinc reagent were chemoselectively formylated with S-Ph thioformate PhSCHO to yield aryl aldehydes ArCHO (Ar = 4-NCC₆H₄, 4-EtO₂CC₆H₄, 4-i-Pr₂NCOC₆H₄, 4-ClC₆H₄, 4-BrC₆H₄, 3-ClC₆H₄, 3-BrC₆H₄, 4-MeOC₆H₄, 1,3-benzodioxol-5-yl, 4-HOC₆H₄, 4-Me₂NC₆H₄, 2-MeC₆H₄, 2-MeOC₆H₄, 2,4,6-Me₃C₆H₂, 2-naphthyl, 1-naphthyl, 2-thienyl, 2-benzofuranyl, 1-Me-5-indolyl) and trans-cinnamaldehyde in 56-97% yields. Using deuterated and ¹³C-labeled deuterated and ¹³C-labeled S-Ph thioformate, 4-DCOC₆H₄CN and 4-BrC₆H₄¹³CH:CH₂ were prepared in high isotopic purities by this method.

Bock, Hans published the artcileRadical ions. 89. One-electron oxidation of diaryl disulfides with aluminum trichloride/dichloromethane, SDS of cas: 77189-99-2, the publication is Phosphorus, Sulfur and Silicon and the Related Elements (1992), 68(1-4), 261-91, database is CAplus.

The single-electron oxidation of 14 alkyl and alkoxy-substituted diaryl disulfides by AlCl₃/H₂CCl₂ has been investigated by ESR/ENDOR spectroscopy. The radical cations observed prove the following skeletal rearrangements: those with ring hydrogens in ortho positions to the disulfide bridge preferentially form thianthrene derivatives The isomeric dinaphthyl disulfides react differently, the 2,2′-isomer yielding the dibenzothianthrene radical cation and the 1,1′-isomer the well-known naphthalene-1,8-disulfide radical cation. For all diaryl disulfides with completely alkyl- or methoxy-blocked ortho positions, oxidative desulfuration is observed As substantiated by addnl. ²D and ³³S isotope marking, bis(3,5-dimethoxyphenyl) disulfide gives both the thianthrene derivative and, by desulfuration, the radical cation of the monosulfide. Accompanying cyclic voltammetric and photoelectron spectroscopic measurements prove that all ESR spectroscopically detected radical cations result from compounds Ar-S-Ar, Ar-SS-Ar and Ar(S)₂Ar with rather low oxidation or ionization potentials and thus suggest that the most easily oxidized paramagnetic species is observed in the rather complex product mixtures

Stereoselective glycosylation remains the main challenge in the chem. synthesis of oligosaccharides. Herein we report a simple method to convert thioglycosides into ¦Â-sulfonium ions via an intramol. alkylation reaction leading to highly selective glycosylation for a variety of glycosyl acceptors. The influence of the thioglycoside substituent and the protecting group pattern on the glycosyl donor was investigated and showed a clear correlation with the observed stereoselectivity.

Wang, Ping published the artcileEncouraging progress in the ¦Ø-aspartylation of complex oligosaccharides as a general route to ¦Â-N-linked glycopolypeptides, Formula: C9H12O3S, the publication is Journal of the American Chemical Society (2011), 133(5), 1597-1602, database is CAplus and MEDLINE.

Described herein is a method for the joining of complex peptides to complex oligosaccharides via an N-linkage. The ¦Ø-aspartylation is conducted by coupling fully deprotected glycosylamine with a peptide containing a unique thioacid at the ¦Ø-aspartate carboxyl. In the presence of HOBT, under conditions that, in principle, allow for oxidation, complex components are combined in encouraging yields to produce structurally and stereochem. defined N-linked glycopolypeptides wherein the carbohydrate domain can be quite complex. Various mechanisms for oxidative coupling are proposed.

A simple procedure to prepare a variety of largely unknown unsym. substituted di-Ph sulfides in high yield, by coupling equimolar amounts of arenesulfenyl chlorides with appropriate aromatic substrates in EtNO₂, is reported. Furthermore, a suitable synthetic route for introducing under mild conditions the mercaptide group into strongly activated substrates is described. Thiophenols I (R¹ = H, Cl) were prepared in good yields via a 2-step synthesis by Fe-catalyzed sulfuration of benzenes II with S₂Cl₂ in CS₂ to give polysulfides III (R¹ = H, x = 3; R¹ = Cl, x = 2), which were reduced with Zn and HCl in C₆H₆.
