GDCh Kolloquium - Professor Dr. Olivier Mentré
What layered iron compounds can offer, and more ... I will introduce recently-found 2D inorganic compounds based on layers of Fe2+ (S=2) ions, in order to highlight how they form a unique platform for new paradigms on spin-dynamics and magneto-dielectric couplings. Here, depending on the crystal structure, the spin-degrees of freedoms and fine anionic compositions are the key-ingredients to tune the exchanges, crystal field ... etc. Especially, I will show in a specific 2D-Ising-ferromagnet (BaFe2(PO4)2) the occurrence of giant magneto-crystalline anisotropy. It results in the collective freezing of magnetic domains which mediates the passage from a soft to a ‘super-hard’ magnet. This unique situation offers various unexpected peculiarities including the ability to imprint any unreturnable magnetization to the sample within simple temperature/field cycles.

GDCh Kolloquium - Professor Dr. Jieping Zhu
Catalytic Enantioselective Pictet-Spengler Reaction of Ketones: Development and Applications in the Total Synthesis of Indole Alkaloids The asymmetric Pictect-Spengler reaction (PSR) between tryptamine and aldehydes is now well-developed. Conversely, catalytic enantioselective PSR of ketone is essentially unexploited. In this presentation, we will present our work on the catalytic enantioselective PSR of tryptamine with 1,2-diones, α-ketoesters and α-ketoamide for the synthesis of enantioenriched 1,1-Disubstituted tetrahydro-β-carboline (THBC) and their application in the total synthesis of monoterpene indole alkaloids.
