Biologically-active small molecules with gamma-arylamine functionality via site-selective C-H functionalization
A novel synthetic methodology that uses free amines as directing groups to achieve site-selective C-H functionalization, enabling rapid access to gamma-arylamine chemical space. This approach eliminates the need for elaborate protecting/deprotecting or late-stage amine-installation techniques, providing modular access to compound libraries for structure-activity relationship studies in drug discovery.
Overview
This research proposes a novel synthetic methodology for accessing biologically-active small molecules bearing gamma-arylamine functionality. By leveraging free amines as directing groups to achieve site-selective C-H functionalization, the approach dramatically reduces the time required to explore novel chemical space. The method eliminates the need for elaborate protecting and deprotecting steps or late-stage amine-installation techniques that traditionally slow drug discovery workflows.
The core value proposition is rapid elaboration of amine chemical space through the formation of new C-C bonds, providing highly modular access to compound libraries that are directly relevant for structure-activity relationship (SAR) studies. This enables pharmaceutical and biotechnology researchers to build and screen diverse molecular libraries more efficiently.

Technology readiness level
This research is at an early stage, presenting a research hypothesis and basis for a new synthetic methodology. The approach is being developed at the University of Toledo with the goal of demonstrating that free amines can effectively serve as directing groups for site-selective functionalization. Further validation work is needed to establish the scope, generality, and practical utility of the methodology across diverse substrate classes.
