We have synthesized a series of hybrid compounds combining the pharmacophoric redox moieties of vitamin E and key features responsible for the antiarrhythmic properties of the class I antiarrhythmics procainamide and lidocaine. Procainamide analogue (2a) and lidocaine analogues (14a) and (14b) are very strong inhibitors of lipid peroxidation. All analogues tested at 100 or 30 μM enhanced the post ischemic recovery without inducing ventricular fibrillations while there was no evidence in our experiments for drug-induced pro-arrhythmia. In addition, they induced a widening of the QRS intervals. Our data suggest that the efficacy of the new compounds in preventing reperfusion arrhythmias could be attributed to their combined effects involving inhibition of free radical mediated damage coupled with antiarrhythmic properties.
Allylation of nitrosobenzene with pinacol allylboronates. A regioselective complement to peroxide oxidation

Addition of nitrosobenzene to pinacol allylboronates leads to oxidation of the organoboron with concomitant rearrangement of the substrate alkene. This reaction appears to proceed by allylboration of the nitroso group in analogy to carbonyl and imine allylation reactions. Remarkably, the N-O bond is cleaved during the reaction such that simple alcohols are the final reaction product.
EFFECT OF THE STRUCTURE OF SUBSTITUTED PROPARGYL AND ALLYL ALCOHOLS ON THE RATE OF THEIR LIQUID PHASE HYDROGENATION ON A Pd-Ru ALLOY MEMBRANE CATALYST

The rates of hydrogenation of substituted propargyl and allyl alcohols in the liquid phase on a Pd-Ru alloy membrane catalyst are described by a two-parameter Taft equation which takes into account the inductive and steric effects of the substituents.The values of the parameters at 363 K with H2 at atmospheric pressure are: ρ* = -0.20, δ = 0.10 and ρ+ = -1.1, δ = 1.3 respectively.
