"Synthesis of Cyclic Compounds by Organocatalytic/Multicomponent Reactions Sequence and Photochemical Approaches"
Prof. Márcio Weber Paixão - UFSCar
Data: 13/06 - quinta-feira
Horário: 16:00 h.
Local: Auditório "Inés Joekes".
Resumo: In this talk, we are going to highlight our results that combine the diversity and complexity-generating character of MCRs with the high stereoselection of organocatalysis for the synthesis of enantiomerically enriched compounds. The reaction sequences comprise the asymmetric aminocatalytic functionalization of α,β-unsaturated aldehydes followed by isocyanide-MCRs with such oxo-components as chiral inputs. These methods, provide a convergent and stereoselective way of producing natural product-like compounds such as hydroquinolines, chromenes, tetrahydropyridines, epoxy- and depsi-peptides.
Furthermore, visible-light-mediated radical cascade reaction towards the access of densely decorated heterocyclic scaffolds will be also disclosed - these strategies feature mild reaction conditions, broad substrate scope and high functional group tolerance affording heterocycles in generally good chemical yields.
