Photoinduced Three-Component Reaction: A Convenient Access to 3-Arylacetals or 3-Arylketals
摘要:
A mild and versatile method for the photoinduced three-component synthesis of 3-arylacetals and ketals is presented. Desired targets are smoothly obtained by irradiating aromatic halides or esters in alcohols, in the presence of vinyl ethers.
A convenient photochemical flow protocol for the formation of aryl‐carbon bonds via photogenerated phenyl cations has been developed. A wide range of phenylated products, including biaryls, allylarenes, 2‐arylacetals and benzyl γ‐lactones, was smoothly synthesized in satisfactory yields under metal‐free conditions. The adoption of a flow reactor often allowed us to adopt higher concentrations of substrates
