A method of synthesis of para-substituted benzoate esters and acids is provided, wherein the para-substituted regioisomer is obtained substantially free of the meta-substituted impurity, the method comprising contacting a coumalate ester or acid and an un activated alkene at elevated temperature in the presence of a metal oxidation catalyst and an oxidant. The metal oxidation catalyst can be palladium, such as palladium on carbon, and the oxidant can be the oxygen gas in ambient air. The reaction can be carlied out without solvent or in high boiling hydrocarbon solvents such as mesitylene. When the un activated alkene is a monosubstituted alkene, yields of at least about 50 or 60% of para-substituted ester and acid products, respectively, are obtained, substantially free of the regioisomelic meta-substituted impurity.

The present invention is directed to indole derivatives, pharmaceutical compositions containing them and their use in the treatment and/or prevention of disorders and conditions ameliorated by antagonizing one or more glucagon receptors, including for example metabolic diseases such as Type II diabetes mellitus and obesity.
α,α-Dideuterio benzyl alcohols are importantbuildingblocks for the synthesis of deuterium-labeled medicines and agrochemicals. We have developed the first general single-electron transfer reductive deuteration of readily commercially available aromatic esters for the synthesis of α,α-dideuterio benzyl alcohols using benign D2O and a mild single-electron donor SmI2. This operationally convenient method
