WebIn my Master's Dissertation, under guidance of the Prof. Dr. Alessandro Bolis Costa Simas, I worked with Palladium-Catalyzed Cross-Coupling Reactions (Heck, Stille, Sonogashira, Tsuji-Trost) aiming synthesis of alkaloid scaffolds of biological interest. WebResults and Discussion. Following our interest in Tsuji-Trost reactions involving isocyanide based MCRs (Dos Santos and El Kaïm, 2014; Cordier et al., 2015; El Mamouni et al., 2016), we decided to explore the behavior of Ugi adducts dianions toward allyl acetate.Besides the efficiency and regioselectivity issues of the reaction of these dianions with π-allyl …
