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 ...

Oxalates as Activating Groups for Alcohols in Visible Light Photoredox Catalysis: Formation of Quaternary Centers by Redox-Neutral Fragment Coupling. [PDF]
, 2015 Alkyl oxalates are new bench-stable alcohol-activating groups for radical generation under visible light photoredox conditions. Using these precursors, the first net redox-neutral coupling of tertiary and secondary alcohols with electron-deficient ...

Angewandte Chemie, EarlyView.A complexity‐generating intramolecular alkene diamination constitutes the pivotal step in the enantioselective synthesis of the title natural products featuring a strained, cage‐like pentacyclic architecture. Abstract Among more than four thousand monoterpene indole alkaloids (MIAs) isolated to date, only a few feature a 2,2,3‐trisubstituted indoline ...

Angewandte Chemie, EarlyView.Ni: neue Lösung für asymmetrische C(sp3)‐H‐Aktivierung. Die stereoselektive Synthese vollständig kohlenstoffsubstituierter quartärer Stereozentren gelingt durch eine enantioselektive C(sp3)‐H‐Arylierung unter Verwendung eines Ni‐Katalysators auf der Basis eines BINOL‐Derivaten.
