Organocatalytic Enantioselective Addition of Malonates to Cyclic Imines: A Short Total Synthesis of Tetraponerine T‐1

Angewandte Chemie, EarlyView.
A stereoselective functionalization method of cyclic imines under mild organocatalytic conditions was developed. Bifunctional cinchona alkaloid catalysts combined with carefully optimized reaction conditions to suppress background reactivity enabled highly enantio‐ and diastereoselective addition reactions of malonates to cyclic imines.

A Multi‐Stimuli Transformational Network of Benzil‐Based Pd(II) Assemblies

Angewandte Chemie, EarlyView.
Incorporation of a flexible and chemically reactive benzil backbone into the ligand structure allows it to access multiple conformations, enabling the formation of diverse homo‐ and heteroleptic Pd(II) assemblies with different nuclearities and topologies.

A Blue Emissive Heavy Atom‐Free Multiresonant Thermally Activated Delayed Fluorescent Emitter Shows Ultra‐Fast Reverse Intersystem Crossing

Angewandte Chemie, EarlyView.
The extended π‐system and low‐lying n‐π∗ transition endow DDOBDiKTa with a synergistic combination of strong spin‐orbit coupling, small reorganization energy and small ΔEST, enabling this blue boron‐nitrogen‐carbonyl hybrid emitter to achieve a fast kRISC of 6.34 × 106 s−1 together with OLEDs showing small efficiency roll‐off, with EQEmax/EQE10000 of ...

Serial protein crystallography in cellulo

Elucidation of high-resolution three-dimensional protein structures via X-ray crystallography requires protein crystals for signal enhancement. Protein crystals have been observed in living cells from all domains of life. This cumulative dissertation refines and expands a systematic approach for crystallization of recombinantly introduced proteins in ...
