- Pd/C-Catalyzed Cyclizative Cross-Coupling of Two ortho-Alkynylanilines under Aerobic Conditions: Synthesis of 2,3′-Bisindoles
Dr. Bo Yao, Dr. Qian Wang and Prof. Dr. Jieping Zhu
Article first published online: 30 MAR 2015 | DOI: 10.1002/chem.201501020
Good to excellent yields of the 2,3′-bisindoles 3 were obtained, through the formation of three chemical bonds (two CN, one CC), in the Pd-catalyzed reaction of two o-alkynylanilines 1 and 2 under mild aerobic conditions. Mechanistic studies suggested that the two catalytic cycles leading to two indole rings were temporally separated. The aminopalladation of 3-alkynylindoles, the product of the first catalytic cycle occurred only after all the N,N-dialkyl-o-alkynylanilines 1 were consumed. This work represents a rare example in which Pd/C was used as a pre-catalyst for the PdII-catalyzed oxidative transformations.

Model meets enzyme: DFT calculations and XAS investigations on a truly biomimetic model for the cysteine dioxygenase reveal that the sulfinate product is bound in a η2-O,O-binding mode (see scheme). This provides the first experimental support for corresponding suggestions that had been made previously for the enzyme itself.
- Liquid-Crystalline Properties of trans-A2B2-Porphyrins with Extended π-Electron Systems
Dr. Mirosław Salamończyk, Dr. Damian Pociecha, Dr. Agnieszka Nowak-Król, Dr. Dominik Koszelewski, Prof. Daniel T. Gryko and Prof. Ewa Górecka

Smectic porphyrins: The replacement of two meso-aryl groups of porphyrins with phenylethynyl or naphthylethynyl substituents increases the melting points of the resultant porphyrins by ∼100 °C and has allowed thermotropic liquid crystallinity to be demonstrated, including a unique switch from columnar to smectic phase.

One step to success! Just one step and a facile and efficient synthetic procedure leads to 5,6-dihydro-11H-pyrido[3,2-i]-1-azacarbazoles with highly potent antitumor activity. The aromatic substituent is cleaved easily gaining access to the corresponding hitherto unknown tetracyclic scaffold (see scheme; DMPU=1,3-dimethyl-3,4,5,6-tetrahydropyrimidin-2-(1H)-one.).
- Surface-Tuned Electron Transfer and Electrocatalysis of Hexameric Tyrosine-Coordinated Heme Protein (HTHP)

Heme theme: Electrochemistry and QCM were used to characterize hexameric tyrosine-coordinated heme protein (HTHP) immobilized on bare carbon or on Au electrodes modified by differently charged self-assembled monolayers. Experimental results are in line with theoretical calculations; HTHP at negatively charged surfaces shows both direct electron transfer of the heme centers and bioelectrocatalysis.
