Comprehensive Mapping of Compositional Dynamics in the Formose Reaction Network

Angewandte Chemie, EarlyView.
Mass spectrometric mapping of target and non‐target products in the formose reaction network was achieved using van Krevelen diagrams and Kendrick mass defect plots. The developed visualization framework offers a powerful means to guide rational strategies for reaction control.

Pyridine Into Pyrrole Transformation Induced Within the Confinement of the Macrocycle

Angewandte Chemie, EarlyView.
This work demonstrates the nontrivial reactivity of pyridine incorporated into a porphyrin framework. The most significant achievement is the contraction of the six‐membered ring to a pyrrole ring, which is a phenomenon of great interest to researchers in this field.

Unexpected Dual Function of Plant YUCCA Enzymes Links Chlorophyll Catabolism to Auxin Homeostasis

Angewandte Chemie, EarlyView.
YUCCA enzymes are well known to catalyze the main step of auxin biosynthesis in plants. Here, a hitherto undescribed dual function was discovered, revealing that some YUCCAs also act in chlorophyll degradation. In vitro feedback regulation furthermore suggests a link between chlorophyll degradation and hormone homeostasis and a physiological role of ...
