We have important changes regarding the members of the group. Gergely Tolnai has successfully applied for a Post doc position in the group of prof. Berit Olofsson. In April he moved to Sweden with his family.

At the same time, we welcomed two new members: Réka Adamik and Mátyás Timári, both working on their BSc studies.Also, we are glad to announce that we have a new-old visiting professor from the USA, prof. Timothy Peelen. He has already been here in 2013 for 6 months. Now, he brought 2 students with him to work with us for 2 months: Cody Lloyd and Darnell Pierre.

Efficient Direct 2,2,2-Trifluoroethylation of Indoles via C-H Functionalization, Gergely László Tolnai, Anna Székely, Zita Makó, Tamás Gáti, János Daru, Tamás Bihari, Andras Stirling and Zoltán Novák, Chem. Commun. 2015, DOI: 10.1039/C5CC00519A

A novel highly C3 selective metal free trifluoroethylation of indoles using 2,2,2-trifuoroethyl(mesityl)-iodonium triflate was developed. The methodology enables the introduction of a trifluoroethyl group in a fast and efficient reaction under mild conditions with high functional group tolerance. Beyond the synthetic developments, quantum chemical calculations provide a deeper understanding of the transformation.

Copper-Catalyzed Oxidative Ring Closure of ortho-Cyanoanilides with Hypervalent Iodonium Salts: Arylation–Ring Closure Approach to Iminobenzoxazines, Klára Aradi, Zoltán Novák, Adv. Synt. Catal. 2015357, 371-376. DOI: 10.1002/adsc.201400763

A novel, highly modular synthetic methodology with high functional group tolerance was developed for the construction of iminobenzoxazine derivatives from ortho-cyanoanilides and diaryliodonium triflates via an oxidative arylation–cyclization path. The reaction is supposed to involve the formation of highly active aryl-copper(III) species. In this novel transformation, copper(II) triflate was used as catalyst in 1,2-dichloroethane or ethyl acetate and the reaction takes place at 75 °C in 2–16 h.

Synthesis and Transformations of Oxygen Heterocycles, Zoltán Novák, András Kotschy. Topics in Heterocyclic Chemistry 2014. DOI: 10.1007/7081_2014_136

The recent developments in the transition metal-catalyzed synthesis and transformations of such oxygen-containing heteroaromatic systems are reviewed, where the oxygen is part of a five-membered ring.

Fruzsi received PhD. degree

Fruzsi successfully defended her PhD thesis. Congratulations!

The Conference of Scientific Students’ Associations (TDK) was organized this year too at ELTE. Considering the points of thesis and the presentation Márton Zwillinger performed in the first place and Dániel Lasányi received the third prize. Congratulations to them!
The next challenge will come at the National Conference of Scientific Students’ Associations (OTDK) in Veszprém (2015 april 9-11).
