Synthia – Proven and Published

To validate the capabilities of Synthia in the lab, we conducted an experiment with six chemists to synthesize several high-value molecules under strict parameters.

Evaluation Parameters:

  • Chemists were free to customize search criteria according to their own “synthetic style” and choose their preferred route
  • Deviations from proposed transformations were not permitted
  • Reaction optimization was fully expected and allowed
  • The synthesis had to be completed in 8 weeks


  1. Installation of the key hydroxyethyl side chain was done at an early stage in the synthesis providing early confidence in the route
  2. Added the finished product to the catalog
  3. Successfully utilized route to establish analogs
  1. Overall yield increased by 500%
  2. Significant cost savings anticipated in production batch
  3. Removed one reaction step from overall synthesis pathway
  1. 50% cost savings
  2. Increased yield from 1% to 61%
  3. Eliminated chromatography from all but the final step of the synthesis
  4. Removed one reaction step from overall synthesis pathway

  1. Previous attempts repeatedly failed following literature methods
  2. Obtained a 20% isolated yield over 5 steps
  1. 35% cost savings
  2. 70% increase in yield
  3. Removed three reaction steps from overall synthesis pathway
  1. Never attempted due to patent controls
  2. Developed an alternate patent-free pathway
  3. Added the finished product to the catalog
