Corley, L. S. published the artcileHaloaldehyde polymers. 16. Stabilization of anionically-prepared polychloral by end-capping with decomposable cations and other additives, Formula: C3H9ClOS, the publication is Polymer (1979), 20(12), 1535-47, database is CAplus.

Completely or partially stable polychloral [25154-92-1] was obtained by anionic cryotachensic polymerization of Cl₃CCHO in the presence of alkylating or acylating agents, e.g. Me₂SO₄ [77-78-1]. Stabilization was also effected by polymerization using salts with easily decomposed cations as anionic initiators. Sulfonium salts, e.g. Me₃S⁺Cl^– [3086-29-1] and [Me₂S⁺CH₂Ph]Br^– [14182-15-1], and iodonium salts, e.g. Ph₂I⁺Cl^– [1483-72-3], were effective although quant. stabilization was not achieved. Polychloral with improved stability was also obtained using certain amide acetals, e.g. Me₂NCH(OMe)₂ [4637-24-5], as initiators.

Seno, Manabu published the artcilePreparation, properties, and x-ray photoelectron spectra of palladium(II) and platinum(II) complexes of amine imides aminimides and sulfur ylides, Recommanded Product: trimethyloxosulphonium chloride, the publication is Journal of the Chemical Society, Dalton Transactions: Inorganic Chemistry (1972-1999) (1977), 751-7, database is CAplus.

Amine imides RMe2N+N-COR1 (R = PhCH2, p-O2NC6H4CH2; R1 = Me, Et, Ph) and the S ylides Me2S+(O)C-HCOPh with Pd(II) and Pt(II) halides gave ylide-metal complexes PdCl2L2 (L = amine imide), PtCl2[Me2S+(O)C-HCOPh]SEt2, and MCl2[Me2S+(O)C-HCOPh]2 (M = Pd, Pt). IR, 1H and 13C NMR, and x-ray photoelectron spectra indicated that the coordination of the ylide to the metal was through the nucleophilic N+ or C- atom as simple terminal ligands. Cis-PtCl2[Me2S+(O)C-HCOPh]SEt2 released SEt2 in Me2SO giving PtCl2[Me2S+(O)C-HCOPh] which was chelated through the carbanion C and the sulfonium O of the ylide. The thermal properties of the complexes were examined by thermal gravimetric anal. and the nature of the bonding was discussed.

Matsuda, Akira published the artcileNucleosides and nucleotides. LXVI. Synthesis of 8,6′-cyclo-6′-deoxyhexofuranosyladenines: adenosines fixed in an anti-conformation, SDS of cas: 5034-06-0, the publication is Chemical & Pharmaceutical Bulletin (1986), 34(4), 1573-8, database is CAplus.

For studies of the conformation of nucleosides around the glycosyl linkages, the carbon-bridged cycloadenosines I (R = OH, R¹ = H; R = H, R¹ = OH) were prepared by the following route. Treatment of N⁶-benzoyl-2′,3′-O-isopropylideneadenosine 5′-aldehyde with dimethyloxosulfonium methylide afforded the 5′,6′-anhydrohexofuranosyladenine II, which was treated with thiophenoxide to give the diastereomeric 6′-phenylthio derivatives III. Photoirradiation of III followed by 5′-O-acetylation afforded III. Attempted synthesis of a 8,7′-cycloheptofuranosyl derivative by way of photolysis of a 7′-phenylthioheptofuranosyladenine resulted in the formation of 5′,6′,7′-trideoxy-2′,3′-O-isopropylidene-β-D–ribo-heptofuranosyladenine. The nature of the CD spectra of I is discussed.

Li, Feng published the artcilePolymethylene Brushes via Surface-Initiated C1 Polyhomologation, Quality Control of 5034-06-0, the publication is Journal of the American Chemical Society (2021), 143(47), 19873-19880, database is CAplus and MEDLINE.

Surface-initiated polymerization reactions are a powerful tool to generate chain-end-tethered polymer brushes. This report presents a synthetic strategy that gives access to structurally well-defined hydrocarbon polymer brushes of controlled mol. weights, which can be further modified to generate more complex surface-attached polymer architectures. The hydrocarbon brushes reported in this study are polymethylene brushes that are obtained via surface-initiated C1 polyhomologation of dimethylsulfoxonium methylide. The strategy outlined here is based on the use of an alkylboronic acid pinacol ester initiator, which allows for controlled, unidirectional chain growth by monomer insertion into only the C-B bond of the initiator and which presents the polymerization active group at the growing polymer chain end. This surface-initiated C1 polyhomologation methodol. is compatible with photopatterning strategies and can be used to generate micropatterned polymethylene brush films. Furthermore, conversion of the boronic ester chain-end functionalities to hydroxyl groups allows for selective chain-end modification and enables access to a variety of surface-anchored block copolymer architectures by chain extension via, for example, ring-opening or atom transfer radical polymerization chemistries.

Epoxidation of 5-acetylpyrrolidin-2-one with dimethyloxosulfonium methylide in THF at 20° for 2 h and then 55° for 1 h gave a 78:22 mixture of epoxides I (α-Me, β-Me) (II and III, resp.) whereas in the presence of ZnCl₂ a 23:77 mixture of II and III was obtained. The configuration of these epoxides was determined from the NMR spectra of the corresponding carbonate derivatives IV and by x-ray crystallog. anal. of III.

Lowe, Robert A. published the artcileSynthesis and evaluation of the performance of a small molecule library based on diverse tropane-related scaffolds, Recommanded Product: trimethyloxosulphonium chloride, the publication is Bioorganic & Medicinal Chemistry (2020), 28(9), 115442, database is CAplus and MEDLINE.

A unified synthetic approach was developed that enabled the synthesis of diverse tropane-related scaffolds. The key intermediates that were exploited were cycloadducts formed by reaction between 3-hydroxypyridinium salts and vinyl sulfones or sulfonamides. The diverse tropane-related scaffolds were formed by addition of substituents to, cyclization reactions of, and fusion of addnl. ring(s) to the key bicyclic intermediates. A set of 53 screening compounds was designed, synthesized and evaluated in order to determine the biol. relevance of the scaffolds accessible using the synthetic approach. Two inhibitors of Hedgehog signalling, and four compounds with weak activity against the parasite P. falciparum, were discovered. Three of the active compounds may be considered to be indotropane or pyrrotropane pseudo natural products in which a tropane is fused with a fragment from another natural product class. It was concluded that the unified synthetic approach had yielded diverse scaffolds suitable for the design of performance-diverse screening libraries.
