A new protocol for ring-closing metathesis/isomerization sequence was developed. The reactions of selected dienes were performed in overheated 2-methyltetrahydrofuran at 120 degrees C and provided a wide range of cyclic vinyl ethers and amides with good yields and selectivities. Computational analysis suggests that the relative yield of products depends on a thermodynamically driven process on the basis of relative stabilities of isomers.

BACKGROUND Rectosigmoid endometriosis is an underdiagnosed disease responsible for abdominal pain, transit disorders and rectal bleeding. Two surgical approaches, rectosigmoid bowel resection (segmental or patch) or intramuscular layer dissection (shaving), are available. AIM To assess whether the lesion features observed via preoperative rectosigmoid endoscopic ultrasonography (RS-EUS) might predict the need for bowel resection. METHODS This multicentric retrospective study was conducted on patients with rectosigmoid endometriosis who underwent a curative surgical procedure, evaluated by RS-EUS performed by two trained operators, between January 2012 and March 2018. A univariate statistical analysis was performed on nodules’ RS-EUS features (thickness, width, infiltration of the submucosae, presence of a bump into the digestive lumen and presence of multiple rectosigmoid localizations). A multivariate logistic regression was then performed on the significant results. RESULTS Of the 367 patients, 73 patients with rectosigmoid endometriosis were evaluated by RS-EUS and underwent rectosigmoid surgery. After the univariate analysis was completed, thickness, width and infiltration of the submucosae were identified as potential predictive factors for bowel resection. In a multivariate logistic regression model, only thickness appeared to be a significant [odds ratio (OR) = 1.49, 95% confidence interval (CI): 1.04-2.12, P = 0.028] predictive factor for bowel resection. Receiver operating characteristic analysis performed showed tha t a thickness over 5.20 ram might be used as cut-off with a sensitivity of 76%, a specificity of 81%, and an area under carve = 0.82. The cut-off values for 100% sensitivity and 100% specificity were 0.90 mm and 10.00 mm, respectively. A trend concerning width to predict the need for resection was also observed (OR 1.12, 95% CI: 1.00-1.26, P = 0.054) CONCLUSION The presence of a rectosigmoid nodule of endometriosis greater than 5.20 mm thick on RS-EUS might predict the need for bowel resection.

Recently, experimental design has beaten the traditional optimization approach (one variable at a time) by providing better quality for chromatographic separation using minimal effort and resources. Benzophenone (BZP) and [1-(diphenylmethyl)piperazine] (DPP) were reported to be the most toxic impurities for dimenhydrinate (DMH) and cinnarizine (CIN), respectively. Additionally, there is no reported HPLC method for the simultaneous determination of DMH, CIN and their toxic impurities. A custom experimental design was adopted to estimate the optimum conditions that achieved the most acceptable resolution with adequate peak symmetry within the shortest run time. Desirability function was used to define the optimum chromatographic conditions and the optimum separation was achieved using XBridge (R) HPLC RP-C18 (4.6 x 250 mm, 5 mu m), acetonitrile: 0.1% sodium lauryl sulphate (SLS) in water (90 : 10, v/v) as a mobile phase at flow rate 2 mL min(-1) and UV detection at 215 nm. Method validation was carried out according to ICH guidelines and linearity was achieved in the ranges of 2-25, 1-25, 1-12.5, and 1-12.5 mu g mL(-1) for DMH, CIN, BZP and DPP, respectively. By application of the proposed method to the market dosage form, no interference from excipients was observed. Moreover, the greenness of the method was evaluated using the National Environmental Method Index (NEMI), Analytical Eco-Scale and Green Analytical Procedure Index (GAPI) metrics and the results revealed the green environmental impact of the developed method.

BACKGROUND: The objective of this study was to assess the relationship between inflammation-based scores and prognosis of patients who had undergone mechanical thrombectomy (MT) for large artery occlusion. METHODS: A total of 411 patients were enrolled and inflammation-based scores, such as neutrophil/lymphocyte ratio (NLR), lymphocyte/monocyte ratio (LMR), and monocyte/high-density lipoprotein cholesterol ratio (MHR) were calculated based on laboratory data. Prognoses were evaluated with unfavorable outcome (modified Rankin Scale score of 3-6), symptomatic intracranial hemorrhage, hemorrhagic transformation of infarct, and mortality. Multivariate analyses were performed to explore the relationships of inflammation-based scores with various clinical outcomes. RESULTS: Patients with unfavorable outcome showed higher mean NLR and MHR but lower mean LMR than those with favorable outcome (NLR, 7.32 vs. 3.78, P <= 0.001; MHR, 1.42 vs. 1.15, P = 0.012; LMR, 2.76 vs. 3.70, P = 0.003). In multivariate analysis, higher NLR (>= 5.1) (odds ratio [OR], 1.58; 95% confidence interval [CI], 1.04-2.12; P = 0.014) and higher MHR (>= 1.4) (OR, 1.32; 95% CI, 1.10-1.74; P = 0.028), lower LMR (<2.5) (OR, 1.28; 95% CI, 1.08-1.58; P = 0.032) were independently associated with unfavorable outcome. CONCLUSIONS: After MT, higher NLR, higher MHR, and lower LMR were found in patients with unfavorable outcome. Inflammation-based scores, such as NLR, LMR, and MHR, might be independent factors that can predict outcomes in patients with MT.

The development of C-N bond formation reactions is highly desirable due to their importance in biology and chemistry. Recent progress in 3d metal catalysis is indicative of unique selectivity patterns that may permit solving challenges of chemical synthesis. We report here on a catalytic C-N bond formation reaction-the reductive alkylation of nitriles. Aldehydes or ketones and nitriles, all abundantly available and low-cost starting materials, undergo a reductive coupling to form secondary alkylamines and inexpensive hydrogen is used as the reducing agent. The reaction has a very broad scope and many functional groups, including hydrogenation-sensitive examples, are tolerated. We developed a novel cobalt catalyst, which is nanostructured, reusable, and easy to handle. The key seems the earth-abundant metal in combination with a porous support material, N-doped SiC, synthesized from acrylonitrile and a commercially available polycarbosilane.

We report the synthesis of aromatic germanimines [(HMDS)(2)Ge=NAr] (Ar = Ph, Mes, Dipp; Mes = 2,4,6-Me3C6H2, Dipp = 2,6-iPr(2)C(6)H(3)) and an investigation into their associated reactivity. [(HMDS)(2)Ge=NPh] decomposes above -30 degrees C, while [(HMDS)(2)Ge=NDipp] engages in an intramolecular reaction at 60 degrees C. [(HMDS)(2)Ge=NMes] was shown to rearrange via a 1,3-silyl migration to give [(HMDS){(SiMe3)-(Mes)N}Ge(NSiMe3)] in a 1:7 equilibrium mixture at room temperature. These latter germanimines react with unsaturated polar substrates such as CO2, ketones, and arylisocyanate via a [2 + 2] cycloaddition pathway.

A set of novel Kv7.2/7.3 (KCNQ2/3) channel blockers was synthesized to address several liabilities of the known compounds XE991 (metabolic instability and CYP inhibition) and the clinical compound DMP 543 (acid instability, insolubility, and lipophilicity). Using the anthrone scaffold of the prior channel blockers, alternative heteroarylmethyl substituents were installed via enolate alkylation reactions. Incorporation of a pyridazine and a fluorinated pyridine gave an analog (compound 18, JDP-107) with a promising combination of potency (IC50=0.16 mu M in a Kv7.2 thallium flux assay), efficacy in a Kv7.2/7.3 patch clamp assay, and drug-like properties.

The in-situ formed metallic Cu particles on the ZrO2 surface were prepared and applied to catalyze dehalogenation of a series of aryl bromides to produce corresponding products in 1-octanol with a yield of >99 %. The mechanistic investigation suggests that the Cu(0) nanoparticles served as hydrogen transfer active sites for degrading alcohols and adsorbing aryl bromides at the reaction system. The results showed that the catalyst was efficient with high reusability. The alcohol not only served as a reducing agent for CuO but also a safe green hydrogen donor. This methodology could be used as a powerful, low-cost, and safe technology for reducing halogenated aromatics.
