HPLC of Formula: C8H8O2. I found the field of Chemistry very interesting. Saw the article An unusual formal migrative cycloaddition of aurone-derived azadienes: synthesis of benzofuran-fused nitrogen heterocycles published in 2021.0, Reprint Addresses Sun, JW (corresponding author), Hong Kong Univ Sci & Technol, Shenzhen Res Inst, Dept Chem, Kowloon, Clear Water Bay, Hong Kong, Peoples R China.; Song, LJ (corresponding author), Harbin Inst Technol Shenzhen, Sch Sci, Shenzhen 518055, Peoples R China.; Sun, JW (corresponding author), Hong Kong Branch Chinese Natl Engn Res Ctr Tissue, Kowloon, Clear Water Bay, Hong Kong, Peoples R China.. The CAS is 123-11-5. Through research, I have a further understanding and discovery of 4-Methoxybenzaldehyde.
Aurone-derived azadienes are well-known four-atom synthons for direct [4 + n] cycloadditions owing to their s-cis conformation as well as the thermodynamically favored aromatization nature of these processes. However, distinct from this common reactivity, herein we report an unusual formal migrative annulation with siloxy alkynes initiated by [2 + 2] cycloaddition. Unexpectedly, this process generates benzofuran-fused nitrogen heterocyclic products with formal substituent migration. This observation is rationalized by less common [2 + 2] cycloaddition followed by 4 pi and 6 pi electrocyclic events. DFT calculations provided support to the proposed mechanism.
