Abstract

AbstractThis study describes a method for transforming benzyl Meldrum's acid (BMA) derivatives into aryl propionic acid (hydrocinnamic acid) derivatives using TiO2 P25 or Celite surfaces under mild conditions. This selective decarboxylation and hydrolysis process is particularly effective for enolizable Meldrum's acid derivatives. A key feature of this transformation is its chemooselectivity, particularly with acetylated BMA derivatives, which yield the corresponding aryl propionic acids. The method offers several advantages, including compatibility with a wide range of structurally diverse aryl propionic acids, reliance on inexpensive materials, elimination of bases and neutralizing agents, and a simplified work‐up procedure.
