Effect of α‐Hydrazino Acids on the Performance of H‐Pro–Pro‐Xaa Catalysts in the Conjugate Addition of Aldehydes to Nitroolefins

open access: yesChemistrySelect, Volume 11, Issue 11, 18 March 2026.
The tripeptide Pro‐Pro‐D‐hVal‐OMe, which lacks an acidic group, catalysed the conjugate addition of aldehydes to nitroolefins and afforded γ‐nitroaldehydes in 79–97% yield and 88:14–93:7 e.r. The proposed reaction mechanism relies on the active role of hydrazide NHβ or NHα protons in hydrogen bonding with the reacting species.

The ability to perform a number of ecosystem functions is degraded by the inappropriate damming of agricultural floodplains (by levee construction) or by the continuous urban expansion, where flood protection is justified but at the cost of affecting the environmental stability of the wider landscape.

Collection, Collation, and Comparison of Near‐Earth In Situ CME Boundaries

open access: yesSpace Weather, Volume 24, Issue 3, March 2026.
Abstract Coronal mass ejections (CMEs) drive space weather throughout the heliosphere so knowledge of their internal properties is key to understanding and eventually forecasting their effects. Typically observations are limited to single‐spacecraft encounters sampling one path that may or may not be representative of the overall structure.
