L'empatia nel percorso formativo universitario. Analisi preliminare su un campione di studenti di psicologia
L’obiettivo principale di questo lavoro di tesi è quello di sottolineare e anche promuovere l’importanza che gioca l’empatia nelle relazioni umane, nella comunicazione, nel rapporto medico-paziente sui risultati psicosociali. La tesi è composta da una prima parte, di natura descrittiva, in cui si inquadra l’empatia prendendo in considerazione il suo rapporto esistente con la dimensione del dolore, il comportamento prosociale e antisociale a causa della presenza di specifici deficit dello sviluppo, le differenze di genere esistenti, i contributi delle neuroscienze sociali, come la scoperta dei neuroni specchio, per poi sottolineare come sia importante promuovere l’empatia sia nella formazione degli operatori sanitari sia negli studenti. La seconda parte, invece, di natura sperimentale, descrive lo studio effettuato agli studenti del corso di psicologia attraverso il questionario dell’Interpersonal Reactivity Index (IRI) di Davis per verificare l’esistenza di una differenza di empatia tra i diversi corsi di laurea

This process is believed to take place through in situ generation of a ketene intermediate, followed by intramolecular [2+2] cycloaddition with a pendant enamide. The formation of a ketene intermediate in this process is significant as the reaction conditions employed are analogous to those commonly used in tertiary amine Lewis base catalysis, where the potential intermediacy of ketenes is an important consideration that is often overlooked.PostprintPeer reviewe
Exploiting the Imidazolium Effect in Base-free Ammonium Enolate Generation:Synthetic and Mechanistic Studies

ADS thanks the Royal Society for a Wolfson Merit Award.N-Acyl imidazoles and catalytic isothiourea hydrochloride salts function as ammonium enolate precursors in the absence of base. Enantioselective Michael addition-cyclization reactions using different α,β-unsaturated Michael acceptors have been performed to form dihydropyranones and dihydropyridinones with high stereoselectivity. Detailed mechanistic studies using RPKA have revealed the importance of the “imidazolium” effect in ammonium enolate formation and have highlighted key differences with traditional base-mediated processes.PostprintPeer reviewe

Stereodivergent organocatalytic intramolecular michael addition/ lactonization for the asymmetric synthesis of substituted dihydrobenzofurans and tetrahydrofurans
The authors thank the Royal Society for a University Research Fellowship (A.D.S.), the European Research Council under the European Union’s Seventh Framework Programme (FP7/2007–2013), ERC Grant Agreement No. 279850 (A.D.L.H. and J.E.T.), and the EPSRC (DTA studentship to D.B.) for funding.A stereodivergent asymmetric Lewis base catalyzed Michael addition/lactonization of enone acids into substituted dihydrobenzofuran and tetrahydrofuran derivatives is reported. Commercially available (S)-(-)-tetramisole hydrochloride gives products with high syn diastereoselectivity in excellent enantioselectivity (up to 99:1 d.r. , 99% ee), whereas using a cinchona alkaloid derived catalyst gives the corresponding anti-diastereoisomers as the major product (up to 10:90 d.r., 99% ee). You can have it both ways! A stereodivergent asymmetric Lewis base catalyzed Michael addition/lactonization of enone acids into substituted dihydrobenzofuran and tetrahydrofuran derivatives is reported, giving products with high d.r. and ee (see scheme).Publisher PDFPeer reviewe
