Copper-Catalysed Synthesis of (E)-Allylic Organophosphorus Derivatives: A Low Toxic, Mild, Economical, and Ligand-Free Method.

Organophosphorus compounds are fundamental for the chemical industry due to their broad applications across multiple sectors, including pharmaceuticals, agrochemicals, and materials science. Despite their high importance, the sustainable and cost-effective synthesis of organophoshoryl derivatives remains very challenging. Here, we report the first successful regio- and stereoselective hydrophosphorylation of terminal allenamides using an affordable copper catalyst system.

[Onco'sport testing by patients: Lived experience of patients with cancer practicing adapted physical activity as part of the Onco'sport program, a qualitative study].

Introduction: Physical activity is a major determinant in the prevention of chronic diseases, equally on the side effects of treatments and the consequences of the disease. It improves quality of life, but also reduces morbidity and mortality, and therefore health expenses. A sedentary lifestyle is the fourth cause of premature death in the world, in the context of chronic non-communicable diseases.

Regio- and Chemoselective Double Allylic Substitution of Alkenyl -Diols.

Double allylic substitution is an attractive approach to building molecular complexity from simple starting materials by creating two new bonds in one pot. However, this type of reaction has been doomed by chemoselectivity and regioselectivity issues. In this letter, we describe a new approach to introduce two new C-C, C-N, C-O, or C-S bonds in a chemo- and regioselective fashion.
