Table 2. Oxidative Halogenation of Natural Products^a.

^aAll reactions were carried out using 0.5 mmol of natural product, 0.6 mmol of Selectfluor, and 1.2 mmol of TBAX (Cl, Br) in 2 mL of CH₃CN. For chlorination: 100 °C, 2 h. For bromination: rt, 5 min. Conversions were calculated by ¹H NMR with 1,3-dinitrobenzene as internal standard.
