RSC Desktop Seminars with Brazilian Chemical Society Organic Chemistry Division (10 Sept)

10 September 2020 11:30-13:00, Brazil


Introduction
RSC Desktop Seminars in Organic Chemistry with the Brazilian Chemical Society 2020 are an initiative from the Royal Society of Chemistry and the Brazilian Chemical Society to bring cutting-edge research directly to you!
 
Covid-19 has exposed us to a new reality where the virtual world is much more important than before. In order to keep our students engaged at the frontiers of Organic Chemistry, we have organized a weekly webinar series that is a joint collaboration between the Royal Society of Chemistry (RSC) and the Organic Chemistry Division of the Brazilian Chemical Society (SBQ). It is an alternative way to share work and interact with potential collaborators.
 
The sections will alternate between Brazilian and international speakers, in some cases with the opportunity for a selected Brazilian early career researcher to engage with the audience by presenting their recent independent career developments.

Programme

11:30 Introductions and welcome
11:35 Early Career presentation with Q&A
11:55 Main Speaker with Q&A

TMS-Aryl Trifluoromethanesulfonates in Benzyne Chemistry: Limitations and New Challenges

Benzyne and its derivatives, called arynes, are highly reactive intermediates, with recognized importance in organic chemistry, successfully employed in syntheses of natural products and preparations of functional materials. In this context, TMS-aryl trifluoromethanesulfonates have emerged as an important alternative for the formation of benzyne and arynes under mild reaction conditions, enlarging the scope of benzyne chemistry applications in preparative organic chemistry. However, some limitations related to their synthetic routes still need to be overcome, for example, the requirement for n-butyllithium, that is, a strong and nucleophilic base, as well as the use of trifluoromethanesulfonic anhydride or bis(trifluoromethanesulfonyl)aniline as triflating reagents. Thus, through this lecture we intend to present our advances and some challenges involving the preparation of novel classes of aryne precursors.

Investigations on drug discovery and process development through photoredox and organocatalysis

Catalysis is a key technology in the pursuit of sustentability for a wide range of processes. In the last decades, photoredox and organocatalysis have been inserted in this scenario promoting more direct synthetic routes with optimization of time and energy. In this talk, I will present some recent advances from my research group in this area towards the synthesis of bioactive compounds and the development of processes employing immobilized organocatalysts in continuous flow systems.
 
Speakers
Cristiano Raminelli, Universidade Federal de São Paulo (Diadema), Brazil

Cristiano Raminelli was born in the south of Brazil in 1977. He received his B.Sc. degree in chemistry from the State University of Londrina in 1998. Studying at the University of São Paulo he received his M.Sc. degree in physical organic chemistry with Prof. Antonia T. Amaral in 2001 and his Ph.D. degree in organometallic chemistry with Prof. João V. Comasseto in 2005. He was a postdoctoral fellow at the Iowa State University working with Prof. Richard C. Larock from 2005 to 2006. Returning to Brazil he was a postdoctoral fellow at the University of São Paulo working with João V. Comasseto from 2007 to 2008. In 2008, he joined the chemistry faculty at the Federal University of Greater Dourados. In 2011, he moved to the Federal University of São Paulo where he is presently a professor of organic chemistry. His research interests include the development of methods involving benzyne chemistry and stereoselective synthesis of bioactive compounds.


Fernanda Gadini Finelli, Federal University of Rio de Janeiro, Brazil

Professor Fernanda G. Finelli obtained her PhD degree in 2009 at UNICAMP. During her PhD, she joined Prof. Alois Fürstner at Max-Planck-Institut as visiting student. Then she moved to Princeton to work as a postdoctoral fellow with Prof. David MacMillan, focusing her research on organocatalysis. In 2012, she started her independent career as Assistant Professor at Federal University of Rio de Janeiro. Her research interests include organocatalysis and photoredox catalysis and their applications in the synthesis of bioactive compounds and natural products.
