This work describes the study on a new recyclable reagent, based on a macrocyclic triazole–borane complex. It showed high chemoselectivity for aldehyde reduction and reductive amination over ketones. This selectivity is driven by a noncovalent hydride–proton interaction that stabilizes the transition state for aldehydes but is sterically inhibited in ...

Readily accessible N‐allyl‐N‐2‐bromoallylamines undergo a tandem lithiation–cyclization cascade to furnish highly substituted 3‐azabicyclo[3.1.0]hexanes. The transformation proceeds without transition metals and delivers products with excellent diastereocontrol across a broad substrate range.

A stereodivergent route from D‐mannitol enables access to enantiopure C5‐α‐substituted linezolid analogues with full configurational control. Biological evaluation reveals that α‐substitution abolishes antibacterial activity irrespective of stereochemistry, establishing a strict steric limitation at C5 and highlighting the dominant role of substituent ...

Ten rules for using evidence to guide ecosystem restoration
These 10 rules provide a guidance framework to put into action the best available evidence, ensuring that restoration benefits people and nature. We highlight the importance of knowledge brokering systems in this process, effectively informed and empowered to fulfil their emerging role across existing institutions and new ones dedicated to Science ...

Researchers should move from characterising factors impacting scientific evidence use to identifying and testing interventions to facilitate its use by conservation decision makers. Since these factors are interlinked, implementation and testing of actions that tackle multiple barriers should be prioritised.
