Key Points

  • This research aims to develop a visible-light-induced reaction to synthesize chain elongated cinnamate esters from cinnamic acid.
  • Utilized visible light to induce a reaction between cinnamic acid and diazoester in THF.
  • Examined the formation and ring opening of oxonium ylide to elongate the chain of cinnamic acid esters.
  • Compared the same reaction in MeCN to produce simple esters.
  • Successfully synthesized chain elongated cinnamate esters using visible light and THF.
  • Demonstrated that the same reaction in MeCN yielded simpler esters of cinnamic acid.

Abstract

A visible‐light‐induced reaction of cinnamic acid and diazoester is developed. In the presence of THF, this reaction provided chain elongated cinnamic acid esters via formation and ring opening of oxonium ylide with cinnamic acid. The same light‐induced reaction of cinnamic acid and diazoester in MeCN provided simple esters of cinnamic acid.
