CeCl3·7H2O: An effective additive in ru-catalyzed enantioselective hydrogenation of aromatic α-ketoesters

(Chemical Equation Presented) In the presence of catalytic amounts of CeCl3·7H2O, [RuCl(benzene)(S)-SunPhos]Cl is a highly effective catalyst for the asymmetric hydrogenation of aromatic α-ketoesters. A variety of ethyl α-hydroxy-α-arylacetates have been prepared in up to 98.3% ee with a TON up to 10 000. Challenging aromatic α-ketoesters with ortho substituents are also hydrogenated with high enantioselectivities. The addition of CeCl3·7H2O not only improves the enantioselectivity but also enhances the stability of the catalyst. The ratio of CeCl3·7H2O to [RuCl(benzene)(S)-SunPhos]Cl plays an important role in the hydrogenation reaction with a large substrate/catalyst ratio.

Reliable and versatile synthesis of 2-aryl-substituted cinnamic acid esters

2-Aryl-substituted phosphono acetates can be readily synthesized by a four-step sequence from the respective arenes. Succeeding Horner-Wadsworth- Emmons olefinations provide stereoselectively the 2-aryl cinnamic acid esters even when sensitive moieties are involved. Georg Thieme Verlag Stuttgart.

Synthesis and anti-inflammatory activity of rac-2-(2,3-dihydro-1,4-benzodioxin)propionic acid and its R and S enantiomers

Racemic (R,S)-2-(2,3-dihydro-1,4-benzodioxin-6-yl)propionic acid (3) has been prepared from 2,3-dihydro-1,4-benzodioxin. R-(-)-Pantolactone has been used as auxiliary for the synthesis of R-3 and S-3. The anti-inflammatory properties of the new carboxylic acids are described and compared with other anti-inflammatory agents. The highest activity is exhibited by compound S-3.
