Professor Huang Hanmin's research team from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) proposed a new paradigm of metal electron-shuttle catalysis, which has been pioneeringly employed to achieve alkylative aminomethylation of unactivated alkene for the first time. Their work was published in Nature Catalysis on August 21.
, thereby facilitating the construction of complex molecules. Existing research is often limited to the introduction of C functional groups, or they require the pre-installation of coordinating groups onto the alkenes to stabilize the alkyl-metal intermediates. This undeniably reduces the substrate applicability and step economy of the reaction.
In this study, the team employed a nickel catalyst as the electron shuttle and used N, O-acetals and alkyl halides as the alkylating agents to accomplish the dialkylation of unactivated alkenes. This method demonstrated excellent compatibility with simple alkenes, unactivated alkenes and polysubstituted alkenes.

In major breakthrough, researchers close in on potential preeclampsia cureResearchers have achieved a significant breakthrough in identifying the primary cause and potential treatment for preeclampsia, a severe pregnancy complication. Experts pinpointed a toxic protein named cis P-tau in the blood and placenta of individuals with preeclampsia. The study describes cis P-tau as a pivotal circulating instigator of preeclampsia. An antibody developed in 2012 to target only the toxic protein while leaving its healthy counterpart unscathed is currently undergoing clinical trials in human patients suffering from traumatic brain injury and Alzheimer's Disease. The antibody has shown promising results in animal models and human cell cultures in treating the brain conditions. Upon testing this antibody in mice, the researchers found the all symptoms associated with preeclampsia were corrected.

Researchers uncover unconventional charge carriers in a triangular-lattice Mott insulatorMott insulators are a peculiar class of materials with structures that should theoretically conduct electricity, but that are instead insulators. These materials contain strongly correlated electrons, which can generate highly entangled many-body states marked by unconventional excitations.
