摘要：The synthesis of nitrogen-containing molecules through carbon-nitrogen (C-N) bond formation is critical for the discovery and preparation of medicines, agrochemicals, and materials. Here, we report the direct insertion of a nitrogen atom into unactivated carbon-carbon double bonds to access aza-allenium intermediates, which can be converted either into nitriles or amidine products, depending on the initial alkene substitution pattern. This operationally simple and highly functionally compatibl...

摘要：Deconstructive transformation of carbon-carbon double bonds (C=C) is a pivotal strategy in synthetic chemistry and drug discovery. Despite the substantial advances in olefin metathesis and ozonolysis for natural product synthesis through C=C double-bond cleavage, the catalytic remodeling of complex molecules through C=C double-bond deconstruction has been underdeveloped. We report a heterogeneous copper-catalyzed C=C double-bond cleavage, which enables the remodeling of complex molecules by co...

摘要：Understanding the capacity of forests to adapt to climate change is of pivotal importance for conservation science, yet this is still widely unknown. This knowledge gap is particularly acute in high-biodiversity tropical forests. Here, we examined how tropical forests of the Americas have shifted community trait composition in recent decades as a response to changes in climate. Based on historical trait-climate relationships, we found that, overall, the studied functional traits show shifts of...
