By combining idealized experiments with realistic quantum mechanical simulations of an interface, we investigate electroreduction reactions of HF, water and methanesulfonic acid on the single crystal (111) facets of Au, Pt, Ir and Cu in a variety of aprotic electrolytes.

Leucosceptroids A and B are sesterterpenoids with potent antifeedant and antifungal activities. A more efficient gram‐scale total synthesis of leucosceptroid B and the first total synthesis of leucosceptroid A are presented. The key transformations include an aldol reaction between a substituted dihydrofuranone and an (S)‐citronellal‐derived aldehyde, a SmI2‐mediated intramolecular ketyl–olefin radical cyclization, and final‐stage alcohol oxidation.
