electron‐withdrawing groups. By applying this novel catalytic system, a general protocol for the Rh‐catalysed hydroformylation‐hydrogenation of unsymmetrical internal alkynes, functionalized with a carboxylic acid, was found to furnish aliphatic aldehydes in high regio‐ and chemoselectivities. Control experiments confirm the enzyme‐like supramolecular catalyst mode of action.
The present invention relates to certain novel substituted thiophene compounds and the finding that they display useful efficacy in the inhibition of the p38α MAPK enzyme. This provides for use of the compounds in various treatment methodologies related to MAPK inhibition, including the treatment of inflammation.
gel-supported sodium hydrogen sulfate (NaHSO4/SiO2) or Amberlyst 15 as solid acid catalyst, and then the corresponding 3-acylisoxaszoles were obtained by reacting with alkynes via the 1,3-dipolar [3+2] cycloaddition. These heterogeneous catalysts are easily separable from the reaction mixture and reused. This synthetic method provides a facile, efficient, and reusable production of 3-acylisoxazoles.
