Toward Chromoselective Transformations in Biological Systems: Perspectives and Challenges

open access: yesAngewandte Chemie International Edition, EarlyView.
Controlling biological systems with small‐molecule chromophores has evolved into a powerful strategy and is applied from chemical biology to medicine. However, the complexity of in vivo systems cannot be matched by a single wavelength of light. Developing methods to combine and individually control multiple chromophores is crucial.

Modificările structural-funcţionale ale aparatului fotosintetic la pomii de măr sub acţiunea factorilor interni şi externi de formare

open access: yesAgricultural Science, 2013
The purpose of our investigations was to identify the photosynthetic functional peculiarities of apple variety Florina using the fluorometric method and depending on the leave position on the shoot, presence/absence of the photo-assimilating acceptor ...

Parallel changes in non-photochemical quenching properties, photosynthesis and D1 levels at sudden, prolonged irradiance exposures in Ulva fasciata Delile

open access: yes, 2007
The photosynthetic response to a sudden and prolonged high irradiance exposure and following recovery at low irradiance were studiedwith the aim of investigating the ability to withstand and adapt to high irradiance without prior high light adaptation ...

Study of non-photochemical quenching of clorophyll fluorescence and related photosynthetic parameters in plants and algae [PDF]

open access: yes, 2019
El quenching no fotoquímico es un proceso empleado por plantas y algas para protegerse del exceso de luz y consiste en la desactivación de moléculas de clorofila excitada (Chl*) por conversión interna al estado fundamental (disipación de calor).

Cobalt‐Catalyzed Radical Ligand Transfer (RLT) Enables Remote‐Markovnikov Hydroamination of Alkenes

open access: yesAngewandte Chemie International Edition, EarlyView.
A cobalt‐catalyzed remote‐Markovnikov 1,3‐hydroamination of allyl carboxylates proceeds through MHAT, 1,2‐radical acyloxy migration (1,2‐RAM), and radical ligand transfer (RLT) from a Co‐N intermediate, providing protected amino alcohols. ABSTRACT Amino alcohols are prevalent in pharmaceuticals, agrochemicals, and functional materials, yet ...
