is driven by a novel activation strategy and features a unique Pd(I)-Pd(I) mechanism, involving an iodide-assisted binuclear step to release the product. This method enables β-selective hydroformylation of a large range of alkenes and alkynes, including sensitive starting materials. Its utility is demonstrated in the synthesis of antiobesity drug Rimonabant and anti-HIV agent PNU-32945. In a broader

Compounds, methods of synthesis, and methods of cancer treatment by arylidene-1,3-dioxane-4,6-diones. A Meldrum's acid-based chemistry and hybrid solid-liquid method. The method includes protection of ketone and aldehyde components and simultaneous immobilization on the solid phase, introduction of substituents, grafts and derivatives compatible with the protection, detachment and restoration of active carbonyl reactivity, reaction of ketone library with malonate, reacting of the products with the aldehyde library in liquid phase and separation of the products by preparative HPLC.

An efficient rhodium‐catalyzed enantioselective addition of potassium organotrifluoroborates to nitroalkenes powered by simple chiral sulfur‐olefin ligands is reported. This protocol is applicable to a broad range of 2‐aryl‐, alkyl‐, and heteroaryl‐substituted nitroalkenes, allowing access to diverse chiral β,β‐disubstituted nitroethanes in good to excellent yields with high enantioselectivity under

experiments were performed in supercritical xenon where vibrationalenergy transfer to the bath is comparably slow. The intramolecular equilibration proceeds in two steps. About 15%-20% of the excitationenergy leaves the azulene side within a short period of 300 fs. This component accompanies the intramolecularvibrationalenergyredistribution (IVR) within the azulene chromophore and it is caused by
