Functional group translocation: moving functionalities without changing molecular scaffolds.

Area of Science:

• Organic Chemistry
• Synthetic Chemistry

Background:

• Functional group position critically impacts molecular properties and biological activity.
• Synthesizing positional isomers traditionally requires inefficient, independent synthetic pathways.
• Positional isomers are vital for drug discovery and materials chemistry.

Purpose of the Study:

• To define and review functional group translocation reactions.
• To differentiate translocation from other isomerization processes.
• To highlight recent advances and future directions in the field.

Main Methods:

• Review of recent literature on functional group translocation.
• Categorization of reactions by molecular scaffold, functional group, and migration distance.
• Emphasis on transition metal catalysis and photoredox chemistry.

Main Results:

• Functional group translocation allows direct relocation of functional groups within a molecule.
• These reactions offer a concise strategy for accessing positional isomers from common precursors.
• Advances enable these transformations beyond classical stoichiometric methods.

Conclusions:

• Functional group translocation is a powerful synthetic tool for accessing positional isomers.
• This methodology streamlines synthesis for drug discovery and materials science.
• Further research can expand capabilities in synthesis and applications.
