Peptidthioester und Peptidtriazolderivate durch Duale Modifikation von Peptidthiosulfonaten auf dem Harz

Angewandte Chemie, EarlyView.
Es wird eine Strategie zur dualen Modifikation von Peptiden auf der Festphase vorgestellt, die die S‐Alkinylierung von Peptidthiosulfonaten und eine regioselektive, iridiumkatalysierte Azid‐Thioalkin‐Zykloaddition umfasst. Dieses Verfahren ermöglicht zuverlässig den Zugang zu Peptiden mit komplexen, nicht‐kanonischen Modifikationen und ist mit ...

Durch anomere Amide ermöglichte divergente Synthese unsymmetrischer Harnstoffe, Carbamate, Thioester und Amide aus Aldehyden

Angewandte Chemie, EarlyView.
Eine divergente Aldehyd‐Funktionalisierungssequenz, ermöglicht durch ein anomeres Amid, erlaubt den Ein‐Topf‐Zugang zu unsymmetrischen Harnstoffen, Carbamaten, Thiocarbamaten, Thioestern und Amiden. Entscheidend für diese Transformation ist die Bildung von N‐Boc‐Hydroxamat‐Intermediaten, die als Plattformen für eine orthogonale Aktivierung über Lossen ...

Morphometric analysis of postnatal lung development in the gray short‐tailed opossum (Monodelphis domestica): An ultrastructural study

The Anatomical Record, EarlyView.
Abstract An ultrastructural morphometric analysis of the postnatal development of the lung in the gray short‐tailed opossum (Monodelphis domestica) has been conducted to evaluate the morphofunctional status of this poorly developed marsupial lung immediately following parturition.

Phantom citations: An empirical study of non‐existent and unverifiable references in scholarly literature

Journal of the Association for Information Science and Technology, EarlyView.
Abstract The integrity of scholarly communication depends critically on the accuracy and verifiability of cited references. Citations enable readers to trace prior work, assess evidence, and situate new contributions within the existing literature. However, concerns have emerged regarding the presence of references in published papers that cannot be ...

Differential Elevational Diversity Between Overstory and Understory in Tropical Forests

Biological Diversity, EarlyView.
Tropical forest overstory and understory exhibit contrasting elevational α‐diversity patterns (unimodal vs. bimodal). Community differentiation is driven by species turnover of dominant rather than rare species, highlighting the need for vertically stratified conservation across the full elevational gradient.
