Problem Statement

  • The current market for synthesizing 1-indenone derivatives are complex and multi-step, with limited scope and poor functional group tolerance.
  • They often rely on expensive transition metal catalysts like palladium or gold, which are difficult to recover or reuse, leading to metal impurities in the final product.
  • These methods also suffer from synthetic difficulties, poor stereoselectivity, and metal contamination, which limit their practicality and scalability for industrial applications.
  • There is a need to develop an alternative synthetic pathway for producing 3-acyl-1-indenones, possibly using a metal-free or sustainable catalytic approach, to address these issues.
