Abstract
A molecular I2‐promoted one‐pot synthesis of 2‐aryl benzoxazoles has been developed by using amidoximes rather than the limited 2‐aminophenols or 2‐haloamides as substrates. The amidoxime substrates provided unique and efficient strategies for converting readily available aniline and benzaldehyde precursors into valuable chemicals. This transformation proceeded smoothly under transition‐metal‐free conditions through a sequential oxidative cyclization and ring contraction, and provided a potential route for introducing certain groups at any site of the scaffold.
