A Practical Start-Up Guide for Synthetic Chemists to Implement Design of Experiments (DoE).

Area of Science:

• Synthetic Chemistry
• Chemical Engineering
• Experimental Design

Background:

• Synthetic chemists commonly use one variable at a time (OVAT) for optimizing reaction conditions.
• OVAT is often inefficient, requiring numerous experiments and failing to identify variable interactions.
• Design of Experiments (DoE) is established in industry but underutilized in academic synthetic chemistry.

Purpose of the Study:

• To introduce Design of Experiments (DoE) methodology to synthetic chemists.
• To provide a practical, entry-level guide for implementing DoE in synthetic method development.
• To highlight the benefits of DoE, including reduced experiment count and identification of variable interactions.

Main Methods:

• The study presents DoE as an alternative to OVAT for reaction optimization.
• Worked examples are provided to illustrate the practical application of DoE.
• Focus is on DoE principles relevant to synthetic method development in an academic setting.

Main Results:

• DoE significantly reduces the number of experiments needed for optimization compared to OVAT.
• DoE effectively identifies interactions between different reaction variables.
• Implementation of DoE leads to more efficient and comprehensive optimization of synthetic routes.

Conclusions:

• DoE offers substantial cost and time savings for synthetic chemistry research.
• This guide aims to facilitate wider adoption of DoE in academic synthetic chemistry.
• Adopting DoE can lead to faster and more robust development of new synthetic methods.
