Mechanochem. solid-state synthesis of 2-aminothiazoles, 2-hydrazinylthiazoles, quinoxalines and benzoylbenzofurans via one-pot sequential α-chlorination of ketones followed by base-mediated condensations with thiourea/thiosemicarbazides, o-phenylenediamine and salicylaldehyde resp. under ball-milling conditions was described. Chlorination of ketones proceeded with atom-economical trichloroisocyanuric acid reagent in the presence of p-TSA under ball-milling conditions to give α-chloroketones which was then further used without isolation. The viability of one-pot sequential acid- and base-mediated reactions in the solid state under ball-milling conditions was thus demonstrated.

Taylor, Scott D. published the artcileSynthesis of Methylene- and Difluoromethylenephosphonate Analogs of Uridine-4-phosphate and 3-Deazauridine-4-phosphate, COA of Formula: C6H4ClNO2, the publication is Journal of Organic Chemistry (2006), 71(25), 9420-9430, database is CAplus and MEDLINE.

Cytidine triphosphate synthetase (CTPS) catalyzes the formation of cytidine triphosphate from glutamine, uridine-5′-triphosphate (UTP), and adenosine-5′-triphosphate. Inhibitors of CTPS are of interest because of their potential as therapeutic agents. One approach to potent enzyme inhibitors is to use analogs of high energy intermediates formed during the reaction. The CTPS reaction proceeds via the high energy intermediate UTP-4-phosphate (UTP-4-P). Four novel analogs of uridine-4-phosphate, e.g. I, and 3-deazauridine-4-phosphate (3-deazaU-4-P) were synthesized in which the labile phosphate ester oxygen was replaced with a methylene and difluoromethylene group. The methylene analog of uridine-4-phosphate, was prepared by a reaction of the sodium salt of tert-Bu diethylphosphonoacetate with protected, 4-O-activated uridine followed by acetate deprotection and decarboxylation. It was found that this compound undergoes relatively facile dephosphonylation presumably via a metaphosphate intermediate. The difluoromethylene derivative, was prepared by electrophilic fluorination of protected uridine-4-phosphate. This compound was stable and did not undergo dephosphonylation. Synthesis of the methylene analog of 3-deazaU-4-P, was achieved by ribosylation of protected 4-(phosphonomethyl)-2-hydroxypyridine. Electrophilic fluorination was also employed in the preparation of protected 4-(phosphonodifluoromethyl)-2-hydroxypyridine which was used as the key building block in the synthesis of difluoro derivative These compounds represent the first examples of a nucleoside in which the base has been chem. modified with a methylene or difluoromethylenephosphonate group.

Novell, Arnau published the artcileOctaproline, a conformationally flexible chiral selector in liquid chromatographic enantioseparation, Synthetic Route of 42074-68-0, the publication is Journal of Chromatography A (2014), 109-118, database is CAplus and MEDLINE.

A proline octapeptide-derived chiral selector (CS) end-capped using a pivaloyl group was covalently linked to a silica gel chromatog. matrix by the C-terminal group. The chromatog. behavior of the resulting chiral stationary phase (CSP) using different conditions was compared to those containing 3,5-dimethylphenylcarbamate residues on the proline units. An enantioseparation ability highly dependent on the mobile phase used is observed for these CSPs. When mixtures of alkane/alc. or alkane/ether were used as mobile phase a similar enantioselectivity was obtained. Nevertheless, in the presence of chlorinated solvents, and without a hydrogen bonding donor in the mobile phase, enantioselectivity is extremely reduced. The reversibility of this phenomenon, attributed to a conformational change in the CS, was examined

Herein, authors disclose the Ni-catalyzed ring-opening C-O functionalization of peri-xanthenoxanthenes using Grignard reagents that forms 8-mono-functionalized binaphthols. 1,2-Bis(dicyclohexylphosphino)ethane was the best ligand for alkylations and ICy for arylation. After mechanistic investigations, authors assumed that the reaction proceeds via C-O reduction and subsequent C-O functionalization. To verify the mechanism, the intermediate after reduction was isolated. Moreover, the asym. addition, using 8-octylbinaphthol after optical resolution, was studied.

The dispiropiperazines I [R = CHBrCH₂Br, CH:CH₂, CHMeCH₂Br, CH₂CH₂NHCH₂Ph, (CH₂)₃Ph, (CH₂)₃C₆H₄NO₂–p, and (CH₂)₃C₆H₄N(CH₂CH₂Cl)₂–p] were prepared and tested along with spirobromine (I, R = CH₂CH₂Br) [86641-76-1] and 8 dipiperazinylalkanes II (R = Me, H; X = Cl, Br; n = 2, 3, 6, 10) for antitumor activity in sarcoma-bearing rats. Although spirobromine itself showed high antitumor activity, its analogs were only ∼33% as active or completely inactive. Three dipiperazinylalkanes showed very high activity; the others were inactive. Structure-activity relations are discussed.

Using an umpolung strategy, herein the first intermol. reductive cross-coupling of aryl tri-/difluoroethanones with 2-alkenylpyridines with the aid of a Bronsted acid catalyst upon visible-light irradiation is reported. This metal-free reaction is operationally simple and performed at ambient temperature, allowing access to desired tertiary alcs. with tri-/difluoromethyl groups in moderate to excellent yields. The com. available and easily handled Hantzsch ester effectively serves as an electron donor, as well as a hydrogen atom source.

Herein, we describe the discovery and optimization of a series of potent and selective TRPV4 antagonists. The application of a variety of computational techniques (including Bayesian modeling) at the HTS triage stage enabled the early deprioritisation of likely frequent hitters. The use of methods to pos. prioritise compounds for follow-up screening allowed the rapid identification of a number of interesting TRPV4 antagonist series. The hit-to-lead efforts in one such series, the hydroxypiperidines, will be described.
