Advances in Ligand Development for Wacker-Type Oxidation

Xianwen Zeng, Liping Chen, Wenxuan Wang, Jinquan Zhang et autres

Wacker-type oxidation is a cornerstone catalytic transformation for alkene-to-carbonyl conversion in organic synthesis, with immense industrial and academic impact over six decades. However, the classic Wacker-Tsuji system suffers from inherent limitations, including corrosive chloride reliance, poor regiocontrol, noble metal dependence, catalyst deactivation, …

Metamorphosis of HOSA: from consumable nitrogen donors to transient directing hubs for switchable divergent synthesis

Junpan Luo, Le Chen, Xianwen Zeng, Jinquan Zhang et autres

-sulfonic acid (HOSA) was relegated to the periphery of organic synthesis as a rudimentary, consumable electrophilic aminating agent. Recently, the strategic exploitation of its highly polarized N-O bond and exceptional sulfate leaving group has triggered renewed methodological interests, elevating HOSA from a …

Switchable Access to Quinolines and Isoquinolines via the Diverse Behavior of Transient Directing Groups

Xianwen Zeng, Wenbin Fu, Xiaoxiao Huang, Jun Luo et autres

-sulfonic acid (HOSA)-enabled, switchable C-H functionalization/annulation of acetophenones with α,β-unsaturated ketones is disclosed, providing a tunable one-pot route to either quinoline or isoquinoline derivatives. The identity of the HOSA-derived transient directing group, coupled with solvent and temperature control, dictates the divergent reaction …

Towards Human-level Intelligence via Human-like Whole-Body Manipulation

Guanghui Gao, Jianan Wang, Jinbo Zuo, Junnan Jiang et autres

Building general-purpose intelligent robots has long been a fundamental goal of robotics. A promising approach is to mirror the evolutionary trajectory of humans: learning through continuous interaction with the environment, with early progress driven by the imitation of human behaviors. Achieving this …

Research on wind power load forecasting based on deep learning

Jiong Le, Guige Gao, Xianwen Zeng

To accurately predict wind power load, we need to understand the time series and environmental conditions. A new forecasting model based on Bidirectional Long Short-Term Memory (BiLSTM) can help. The correlation of the wind power load data set is analysed by Spearman's …
