Influence of ESGC Indicators on Financial Performance of Listed Pharmaceutical Companies.

The pharmaceutical industry, concerned about the impact of its activity, has integrated responsible principles and practices with a view to improving its sustainable and financial performance. This study analyzes the relationship between environmental, social, governance, and controversy indicators and financial performance, measured through return on equity (ROA), return on assets (ROE), and Tobin's Q, which are applied to the listed companies in the Nasdaq US Smart Pharmaceuticals Index. This index is composed of 30 international companies with a presence at the global level.

Model of Organizational Commitment Applied to Health Management Systems.

In this paper, we try to build on the problems surrounding the management of human resources in health care organizations worldwide. After the analysis of the reviewed literature, we detected that the scientific community considers several recurring themes that need attention: stress, burnout, and turnover intention. Based on this, we developed a model of organizational commitment that aims to achieve performance and health quality, its main result the establishment of the appropriate management policies in order to avoid the abandonment of the organization through the search for commitment and job satisfaction.

Productivity in religious orders: A management by values applied approach.

Purpose: In this theoretical-empirical study, we analyse work methodologies of Spanish Religious Orders, and their relationship with productivity, efficacy and efficiency.

Design/methodology/approach: In the literature review we have compiled all the applicable theories. Amongst them, Management by Values stands out and has served as the framework for the hypotheses.

Organisational Commitment in Healthcare Systems: A Bibliometric Analysis.

Business organisations are subject to high pressure to ensure their sustainability and competitiveness. In the case of healthcare institutions, moreover, there are unique characteristics where human resource management is of vital importance. The workforce in these institutions is at a critical moment where the shortages of qualified staff, burnout, or job dissatisfaction represent some of the detrimental aspects for the performance of the organisation, and more importantly, they diminish the quality of patient care.

Stereochemical aspects and the synthetic scope of the S(H)i at the sulfur atom. Preparation of enantiopure 3-substituted 2,3-dihydro-1,2-benzoisothiazole 1-oxides and 1,1-dioxides.

Intramolecular homolytic substitution (SHi) on the sulfur atom at acyclic N-(o-bromobenzyl)sulfinamides takes place with a complete inversion of the configuration and provides an excellent tool to connect N-tert-butanesulfinylimines with enantiopure 3-substituted benzo-fused sulfinamides (1,2-benzoisothiazoline 1-oxides) and the related pharmacologically relevant sulfonamides.

Intermolecular alkyl radical additions to enantiopure N-tert-butanesulfinyl aldimines.

The sulfinyl group in (R)-N-tert-butanesulfinyl aldimines provides efficient control of the stereoselectivity in the intermolecular reactions with alkyl radicals. The methodology is applicable to aryl, heteroaryl, benzyl, and alkynyl imines, even those containing CN, CO2Me, COR, and OH groups. The best results are attained with hindered radicals (tertiary and secondary ones) without C═N bond reduction.

Synthesis of 3-vinyl-2,5-dihydrofuran ring system via enyne metathesis.

An efficient route, starting from but-3-en-1,2-diol, is described to synthesize racemic diastereoisomeric (5-ethoxy-4-vinyl-2,5-dihydrofuran-2-yl) methanol derivatives. Acyclic enyne intermediates having the alkyne moiety directly connected to the asymmetric carbon atom of an acetal were obtained in two steps. These reactive substrates were then subjected to ruthenium-catalyzed enyne metathesis to produce the target compounds in racemic form.

Remote stereocontrol mediated by a sulfinyl group: synthesis of allylic alcohols via chemoselective and diastereoselective reduction of gamma-methylene delta-ketosulfoxides.

The efficiency of the sulfinyl group as a remote controller of the chemoselectivity and diastereoselectivity of the reduction of alpha, beta-unsaturated alpha-[2-(p-tolylsulfinyl)phenyl] substituted ketones 1 has been demonstrated in reactions carried out under NaBH4 in the presence of Yb(OTf)3 as the chelating agent. The starting unsaturated ketones have been prepared from the corresponding 2-(p-tolylsulfinyl) benzyl alkyl (and aryl) ketones 2 by insertion of the methylidene group under modified Mannich conditions, exploiting ultrasound irradiation to obtain the aminomethylation adducts and silica gel treatment to produce its complete elimination. Desulfinylation of the reduction products yielded the corresponding vinyl carbinols with high enantiomeric purity.

Remote stereocontrol by sulfinyl groups: reduction of delta-ketosulfoxides.

The reduction of delta-ketosulfoxides constitutes the first evidence of the efficiency of the sulfinyl group to control the stereoselectivity of 1,5-asymmetric induction processes. The use of DIBAL/Yb(OTf)3 or L-Selectride as the reducing agents provides delta-hydroxysulfoxides with the opposite configuration at the hydroxylic carbon in a highly stereoselective way.

Synthesis of Aminocyclitols by Intramolecular Reductive Coupling of Carbohydrate Derived delta- and epsilon-Functionalized Oxime Ethers Promoted by Tributyltin Hydride or Samarium Diiodide.

The intramolecular reductive coupling of a series of simple or polyoxygenated oxime ethers delta- or epsilon-functionalized with bromide, alpha,beta-unsaturated ester, aldehyde, or ketone groups is reported. The cyclization of a nitrile-tethered aldehyde is also studied. These reductive couplings are promoted by tributyltin hydride or samarium diiodide.
