A combined experimental and theoretical study of the thermal [3+2] cycloaddition of carbonyl ylides with activated alkenes

2018

International audience; 4-Benzoyl-3,5-diaryltetrahydrofuran-2,2-dicarbonitriles were first synthesized from 2,2-dicyano-3-aryloxiranes and chalcones at toluene reflux; the 4,5-cis products proved to be predominantly formed and were isolated. Whereas shortened reaction times were observed by using microwave irradiation or catalytic cuprous chloride, no significant stereoselectivity change was in general noticed. Reacting 2,2-dicyano-3-aryloxiranes with 2-cyclopentenone next afforded 3-aryl-4-oxohexahydro-1H-cyclopenta[c]furan-1,1-dicarbonitriles, and the endo stereoisomers were isolated. That no stereoselectivity change was noticed in the presence of cuprous chloride rather suggests an impac…

Développer ses compétences transversales pour réussir ses études en santé

2018

International audience; Cette communication propose une réponse à la question « Quels outils pédagogiques mobiliser, notamment pour l’acquisition des compétences transversales ? ».Nous présentons une expérimentation qui s'est déroulée auprès de 66 étudiants en L2 Sciences pour la Santé à l’Université de Lorraine. La formation d’une semaine, proposée conjointement par les projets IDEFI Remis et TalentCampus en septembre 2017, visait à :- permettre à chacun de découvrir l’importance des compétences transversales ;- travailler son estime de soi ;- développer des compétences de travail en groupe et de communication orale.La L2 Sciences pour la Santé présente la particularité d’accueillir un pub…
