Macrocyclic compounds via novel sigmatropic rearrangement ring-expansion chemistry

Overview

This research presents a novel chemistry-driven synthetic approach to produce macrocyclic compounds containing 1,4-disubstituted arene fragments. The methodology is based on a new [5,5]-sigmatropic rearrangement ring-expansion process, enabling access to structural motifs that have not been previously reported in the literature. The work is motivated by the well-established biological activity of macrocyclic compounds bearing 1,4-disubstituted arenes, such as Vancomycin, one of the most important antibiotic classes. By providing an effective synthetic route to these structures, this research opens pathways to generate new chemical entities for biological testing and pharmaceutical development.

Technical specifications

Core innovation:

• A [5,5]-sigmatropic rearrangement ring-expansion process that converts precursor substrates into macrocyclic products
• Chemistry-driven synthesis approach producing 1,4-disubstituted arene-containing macrocycles
• Generates a series of new structural motifs that were previously inaccessible

Relevance and applications:

• Inspired by Vancomycin and related macrocyclic natural products with known biological activities
• Potential utility for pharmaceutical screening and drug discovery programs
• Provides a new tool for constructing medium and large ring systems bearing functionalized arenes

Technology readiness level

This research is at an early discovery stage. The team has established a novel synthetic methodology based on the [5,5]-sigmatropic rearrangement and is positioned to prepare a series of new structural motifs for biological testing. Further validation work is needed to fully characterize the scope of substrates, optimize reaction conditions, and evaluate the biological activity of the resulting macrocyclic compounds.
