Control over the chain length of the polymethylene block was achieved by adjusting the initial molar ratio of ylide to organoborane. ABA block copolymers of polymethylene-polydimethylsiloxane-polymethylene were synthesized by a similar approach using thexyl borane as the difunctional hydroboration agent.

Collins, Nathan published the artcileFully Automated Chemical Synthesis: Toward the Universal Synthesizer, HPLC of Formula: 5034-06-0, the publication is Organic Process Research & Development (2020), 24(10), 2064-2077, database is CAplus.

Automated peptide and oligonucleotide synthesizers enabled a revolution in mol. biol. and helped pave the way to modern synthetic biol. Similarly, fully automated synthetic chem. could herald a new wave of innovation in biol. and materials sciences by greatly facilitating access to known and novel mols. Here, we report on an automated multistep chem. synthesizer, AutoSyn, that makes milligram-to-gram-scale amounts of virtually any drug-like small mol. in a matter of hours and demonstrate its versatility with the synthesis of ten known drugs. Of the FDA-approved small-mol. drugs for which we were able to compute a synthetic route, 87% are predicted to be synthesized on AutoSyn. Moreover, AutoSyn enables digital synthesis protocols that ensure the reproducibility and transferability of synthesis protocols from one lab to another. If this follows the same evolution as automated peptide and DNA syntheses, it will lead to an exponential increase in chem. innovation across biol. and material sciences.

Kakei, Hiroyuki published the artcileCatalytic Asymmetric Cyclopropanation of Enones with Dimethyloxosulfonium Methylide Promoted by a La-Li₃-(Biphenyldiolate)₃ + NaI Complex, Recommanded Product: trimethyloxosulphonium chloride, the publication is Journal of the American Chemical Society (2007), 129(44), 13410-13411, database is CAplus and MEDLINE.

Catalytic asym. cyclopropanation of enones with dimethyloxosulfonium methylide using a La-Li₃-(biphenyldiolate)₃ + NaI complex is described. The present method is complementary to the previously reported catalytic enantioselective methods in terms of ylides used, and trans products, e.g., I, were exclusively obtained in good yield (96-73%) and high enantioselectivity (99-84% ee). Use of biphenyldiol and NaI additive was essential to achieve high enantioselectivity.

Waszkowycz, Bohdan published the artcileCell-Active Small Molecule Inhibitors of the DNA-Damage Repair Enzyme Poly(ADP-ribose) Glycohydrolase (PARG): Discovery and Optimization of Orally Bioavailable Quinazolinedione Sulfonamides, Name: 2-(Chloromethyl)-5-methyl-1,3,4-thiadiazole, the publication is Journal of Medicinal Chemistry (2018), 61(23), 10767-10792, database is CAplus and MEDLINE.

DNA damage repair enzymes are promising targets in the development of new therapeutic agents for a wide range of cancers and potentially other diseases. The enzyme poly(ADP-ribose) glycohydrolase (PARG) plays a pivotal role in the regulation of DNA repair mechanisms; however, the lack of potent drug-like inhibitors for use in cellular and in vivo models has limited the investigation of its potential as a novel therapeutic target. Using the crystal structure of human PARG in complex with the weakly active and cytotoxic anthraquinone 8a, novel quinazolinedione sulfonamides PARG inhibitors have been identified by means of structure-based virtual screening and library design. 1-Oxetan-3-ylmethyl derivatives 33d and 35d were selected for preliminary investigations in vivo. X-ray crystal structures help rationalize the observed structure-activity relationships of these novel inhibitors.

Singh, Man published the artcileEffect of trimethylsulphoxonium halide surfactants on consolute solutions of immiscible solvents, COA of Formula: C3H9ClOS, the publication is Physics and Chemistry of Liquids (2011), 49(3), 302-308, database is CAplus.

Consolute solution temperatures (CST) ± 0.01 K and corresponding solubilities of phenol-water mixtures with 0.35 millimol kg-1 trimethylsulfoxonium chloride (TMSOC), trimethylsulfoxonium bromide (TMSOB), and trimethylsulfoxonium iodide (TMSOI) cationic surfactants are reported. The halide surfactants (TMSOX, X = Cl-, Br-, I-) decreased the CST by about 1.73-2.18° with 3-5% less mutual mixing as compared to phenol-water mixtures Three -CH3 (methyl) and the chloride (Cl-), bromide (Br-) and iodide (I-) halide ions of surfactants had developed hydrophobic and hydrophilic interactions, resp. The CST data are as TMSOI > TMSOB > TMSOC with corresponding mutual solubilities as TMSOC > TMSOB > TMSOI, with slightly stronger I–water interaction due to induced potential of a large-sized iodide ion. The hydrophobic interactions mildly dominated with smaller sized Cl- anion with slightly higher mutual solubility Comparatively, consolute solutions with surfactants are obtained at slightly lower temperatures with higher mutual mixing.

Jurga, Stefan published the artcileNuclear magnetic relaxation studies in solids, COA of Formula: C3H9ClOS, the publication is Ser. Fiz. (Uniw. im. Adama Mickiewicza Poznaniu) (1980), 58 pp., database is CAplus.

Spin-lattice relaxation times in the laboratory and in the rotating frame are reported for trimethyloxosulfonium fluoride, chloride, bromide and iodide as well as for Me₂SO and Me₂SO₂ over a wide temperature range. A model was developed that makes it possible to analyze the exptl. data on the basis of 4 independent reorientations around 3 3-fold axis and around center of gravity . The following conclusions consistent with the 2nd moment and spin-lattice relaxation results are drawn about reorientational state of cations and mols. The Me group is reorienting about its 3-fold axis at random between 3 equilibrium positions separated by 120° in all the compounds A 3-fold reorientation of all cations around the C₃ axis (designed by S → O bond) occurs. There is dynamical inequivalence of Me groups within the Me₂SO mol. and trimethyloxosulfonium chloride with 1:2 ratio. There is observed translational diffusion in Me₂SO₂. The activation energies for C₃ and C‘₃ reorientations decrease with an increase of an anion ionic radius (with exception of the iodide salt for the last motion).
