Background:

  • Solid-phase synthesis is a crucial technique in drug discovery and materials science.
  • Efficient and versatile linkers are essential for successful solid-phase synthesis.
  • Triazenes offer unique chemical properties as potential linkers.

Purpose of the Study:

  • To investigate the utility of triazenes as "traceless" linkers in solid-phase synthesis.
  • To demonstrate the application of triazene-linked arenes in various chemical transformations.
  • To evaluate the key characteristics of triazene linkers, including accessibility, stability, and regeneration.

Main Methods:

  • Attachment of arenes to a solid support via triazene linkers.
  • Performing organometallic reactions, including Heck reaction and asymmetric dihydroxylation.
