Consultable des del TDXTítol obtingut de la portada digitalitzadaLa síntesi de sulfòxids quirals ha estat investigada teòricament considerant dos dels mètodes més avançats: l'oxidació asimètrica de sulfurs amb peròxid d'hidrogen catalitzada per vanadi i el mètode DAG. El mecanisme d'aquestes reaccions va ser explorat a nivell DFT (teoria del funcional de la densitat) en sistemes models. L'origen de l'enantioselectivitat en els sistemes reals va ser investigat emprant mètodes híbrids QM/MM (mecànica quàntica/mecànica molecular). L'estudi DFT sobre la sulfoxidació asimètrica catalitzada per vanadi va revelar que aquest procés segueix un mecanisme de transferencia directa d'oxigen en que el substrat s'oxida en una única etapa concertada. El ca...
