Network-analysis-guided synthesis of weisaconitine D and liljestrandinine. [PDF]
, 2015 General strategies for the chemical synthesis of organic compounds, especially of architecturally complex natural products, are not easily identified. Here we present a method to establish a strategy for such syntheses, which uses network analysis.

Visible-Light Mediated Activation of 1,3-Dienes and Allenes via Energy Transfers. [PDF]
ChemistryNature has inspired chemists to develop photocatalytic processes that harness visible light, offering alternative reaction pathways beyond traditional thermal methods. Energy Transfer (EnT) is a particularly promising strategy, enabling transformations such as isomerization, deracemization, cycloadditions, and cascade reactions.

A Crystalline Mono‐Coordinate Indium(I)‐Phosphaalkenyl
Angewandte Chemie, EarlyView.The redox neutral carbometallation of a phospha‐alkyne using the dimeric indium(I) compound (InTer)2 is reported. This reaction affords a mono‐coordinate indium(I) compound that can reversibly extrude the phospha‐alkyne upon addition of a Lewis acid. Abstract The synthesis of the mono‐coordinate indium(I) compound In[C(Ad)═PTer] (Ad = 1‐adamantyl, Ter =
