Enantioselektivní allylace dienalů a jejich aplikace v syntéze tiacumicinu / Enantioselective allylation of dienals and their application in tiacumicin synthesisKoukal, Petr January 2018 (has links)
The current methodologies of catalytic enantioselective allylation of aldehydes were studied on conjugated dienals and later on haloacrylaldehydes as the substrates. The resulting enantioenriched homoallylalcohols were prepared by reactions promoted either by commercial Brønsted acid catalysts or by Lewis base catalysts developed by our group, often with high enantio- and diastereoselectivities. Subsequently, the methodology was expanded on catalytic enantioselective crotylation and pentenylation reactions, practically unknown not only with these substrates. The applicability of this synthetic approach was demonstrated on preparation of several natural products or their intermediates.
