We present a metal-free method for α-acetoxyarone synthesis by self-intermolecular oxidative coupling of aryl ketones using I2−tert-butyl hydroperoxide (TBHP). Under the optimum conditions, various aryl ketones gave the corresponding products in moderate to excellent yields. A series of control experiments were performed; the results suggest the involvement of radical pathways. Multiple radical intermediates were generated in situ and the overall process involved several different reactions, which proceeded self-sequentially in a single reactor. A labeling experiment using 18O-labeled H2O confirmed that the oxygen in the product was derived from TBHP, not from H2O in the TBHP solvent.

Tert Butyl Hydroperoxide

An efficient, metal-free oxidative coupling of tetrahydroisoquinolines and 3-fluorooxindoles on water has been developed. Using aqueous tert-butyl hydroperoxide as the oxidant, Et3N as the base, and water as the sole solvent, a variety of 3-fluorooxindoles fully substituted at the 3-position and containing a tetrahydroisoquinoline fragment has been successfully prepared in yields of up to 93% with an anti/syn stereo­selectivity of up to 99:1 under very mild and safe reaction conditions.
