Synthesis and characterization of imine-palladacycles containing imidate “pseudohalide” ligands: Efficient Suzuki-Miyaura cross-coupling precatalysts and their activation to give Pd0Ln species (L = Phosphine)

Dinuclear palladacyclic complexes [{Pd(C^N)(mu-NCO)} 2] (C^N = N-phenylbenzaldimine, Phbz) containing asymmetric imidato units (-NCO- = succinimidate (succ; 1), phthalimidate (phthal; 2), maleimidate (mal; 3), 2,3-dibromomaleimidate (2,3-diBrmal; 4), glutarimidate (glut; 5)) have been readily prepared by reaction between the di-mu-acetate precursor and cyclic imide ligands in a 1:2 molar ratio. Base treatment of the less acidic ligands 2-oxazolidone and delta-valerolactame with KOH/MeOH was required to give analogous -NCO- bridged complexes (6 and 7). Reactions of the dinuclear complexes with tertiary phosphines provide novel mononuclear N-bonded imidate derivatives of the general formula [Pd(Phbz)(imidate)(PR3)] (R = Ph (a), 4-F-C6H4 (b), 4-MeO-C6H4 (c), CH2CH2CN (d)). The application of these novel palladacyclic complexes as precatalysts for the Suzuki-Miyaura cross-coupling reactions of both aryl and benzyl bromides with phenylboronic acid has been examined. The acetate adducts [Pd(Phbz)(CH 3COO)(PR3)] (8a,c) were prepared to assess the role of imidate ligands in catalyst performance. The mononuclear imidate derivatives possess greater activity than the parent dinuclear complexes, exhibiting comparable performance in the cross-coupling of benzyl bromide with arylboronic acids to the best examples reported in the literature. The mononuclear imidate derivatives give a common Pd0Ln intermediate, as inferred by the release of the organic fragment (first reductive elimination product). Catalyst activation occurs by reaction of phenylboronic acid with the palladacycle in the absence of exogenous base (as shown by GC-MS and ESI-MS), with implications for the reliable comparison of catalyst performance across a series of related precatalysts (e.g., how catalyst/reagents are mixed and what is their order of addition). The single-crystal X-ray structures of compounds 4, 7, 1d, 3c, and 8a have been determined.

Recent developments in glycosyl urea synthesis

The area of sugar urea derivatives has received considerable attention in recent years because of the unique structural properties and activities that these compounds display. The urea-linkage at the anomeric center is a robust alternative to the naturally occurring O- and N-glycosidic linkages of oligosaccharides and glycoconjugates, and the natural products that have been identified to contain these structures show remarkable biological activity. While methods for installing the beta-urea-linkage at the anomeric center have been around for decades, the first synthesis of alpha-urea glycosides has been much more recent. In either case, the selective synthesis of glycosyl ureas can be quite challenging, and a mixture of alpha- and -isomers will often result. This paper will provide a comprehensive review of the synthetic approaches to alpha- and -urea glycosides and examine the structure and activity of the natural products and their analogues that have been identified to contain them.

Exposure to pesticides and mental disorders in a rural population of Southern Brazil

Introduction Exposure to pesticides has been associated with mental disorders, especially in occupationally exposed populations, such as farmers. This effect has been attributed to the neurotoxic and endocrine-disrupting activity of pesticides, as suggested by experimental studies. Objective To determine the prevalence of common mental disorders and self-reported depression, and analyze their association with the exposure to pesticides in a rural population resident in the municipality of Dom Feliciano, Rio Grande do Sul, where tobacco farming is the main economic activity. Methodology A cross-sectional study evaluating the prevalence of common mental disorders and self-reported depression in a sample of 869 adult individuals resident in Dom Feliciano, between October 2011 and March 2012 was performed. The evaluation of common mental disorders was performed using the Self-Reporting Questionnaire (SRQ-20), setting a cutoff point of 8 for both genders. A standardized questionnaire was used to obtain information on self-reported depression upon prior diagnosis by a health professional, and self-reported exposure to pesticide. In order to evaluate the association between exposure to pesticides and mental disorders, a non-conditional multivariate logistic regression analysis was performed. Results The prevalence of common mental disorders and self-reported depression in the sample population were 23% and 21%, respectively. Among individuals who reported depression, an increase of 73% was observed in the odds of pesticide exposure at an age equal to or less than 15 years. There was a positive association between self-reported pesticide poisoning and common mental disorders (OR?=?2.63; 95% CI, 1.62-4.25) as well as self-reported depression (OR?=?2.62; 95% CI, 1.63?4.21). Individuals who reported depression had a greater odds of exposure to pyrethroids (OR?=?1.80; 95% CI, 1.01?3.21) and aliphatic alcohol (OR?=?1.99; 95% CI, 1.04?3.83). An SRQ?20???8 was associated with an approximately seven times higher odds of exposure to aliphatic alcohol (95% CI, 1.73?27.53). Self-reported depression positively correlated with a greater period of exposure to dinitroaniline (OR?=?2.20; 95% CI, 1.03?4.70) and sulphonylurea (OR?=?4.95; 95% CI, 1.06?23.04). Conclusion The results suggest that exposure to pesticides could be related mental disorders. However, other common risk factors in tobacco farming, the main local economic activity, cannot be excluded.
