Disconnection

Definition

Disconnection is a strategic approach in retrosynthetic analysis where a complex molecule is broken down into simpler precursor structures, facilitating the planning of a synthetic route. This method allows chemists to visualize potential synthetic pathways and make informed decisions about reagents and conditions needed for synthesis. It helps in identifying the critical bonds that can be cleaved to simplify the synthesis process.
