Fine Tuning of Catalyst Active Sites to Access Advanced Ultrahigh‐Melting Polyolefins

Angewandte Chemie, EarlyView.
A redesign of the active site of the pyridylamido hafnium (Hf) catalysts can enhance the performance of this catalyst family and unlock previously inaccessible polymer structures. When the catalyst is precontacted with allyltrimethylsilane the active species is modified and the catalyst experiences a new life becoming able to polymerize sterically ...

Engineering Rapid Payload Release Rate in 1,6‐Elimination Processes of Self‐Immolative Linkers

Angewandte Chemie, EarlyView.
The payload release rate of self‐immolative linkers was greatly improved through stabilization of an intermediate carbocation, thereby achieving an up to 10 000‐fold improvement in rate constant. Furthermore, lipophilicity was identified as another factor that affects the release rate. This new strategy is applicable to different payloads and different

Biokatalysatoren für die Geranylierung von Peptiden mit Linearen und Zyklischen Prenylgruppen

Angewandte Chemie, EarlyView.
A combination of genome mining, synthetic biology, and biocatalytic assays revealed enzymes that install linear and cyclized prenyl moieties on ribosomally or chemically synthesized peptides. The promiscuity of both enzymes, while being specific for modification of C‐terminal tryptophans, enables enzymatic access to peptide terpenoid hybrids ...
