Redistribution in combinatorial synthesis. A theoretical approach

Area of Science:

• Synthetic Chemistry
• Combinatorial Chemistry
• Chemical Engineering

Background:

• The split-mix method enables high-throughput synthesis but traditionally uses labeled solid supports.
• Labeled supports can be costly and add complexity to the synthetic process.

Purpose of the Study:

• To investigate the feasibility of a tag-free split-mix method for compound synthesis.
• To maintain high productivity and yield without the need for labeled support units.

Main Methods:

• Utilizing unlabeled macroscopic support units arranged in spatially ordered groups.
• Implementing a combinatorial redistribution rule for unit movement between reaction steps.
• Employing computer simulation to track the synthetic history of each support unit.

Main Results:

• Demonstrated that tagging support units is unnecessary for successful split-mix synthesis.
• Identified specific redistribution patterns (serial, semi-parallel, parallel) suitable for the method.
• Showcased that semi-parallel and parallel redistribution strategies significantly accelerate the sorting process.

Conclusions:

• A tag-free split-mix method is viable, preserving high productivity and yield.
• Spatially ordered unlabeled supports combined with computational tracking offer an efficient alternative to labeled systems.
• Optimized redistribution patterns, particularly semi-parallel and parallel, enhance the speed and efficiency of the synthesis.
