With the help of additives (PPh<sub>3</sub> and NaH), air could be directly used as green oxidant to construct prenylated and reverse-prenylated α-hydroxy-oxindoles divergently from the same substrates. In situ esterification of prenylated α-hydroxy-oxindoles allowed subsequent Friedel-Crafts substitutions with diverse nucleophiles to deliver prenyl substituted dimeric or spiro-oxindoles.

With a stable chiral organofluorine probe, and especially with X-ray data of two isolated arene oxides derivatives, we demonstrate that an arene oxide pathway is definitely involved in P450-catalyzed aromatic hydroxylation.

In addition to the model substrate, we also confirmed that an arene oxide intermediate is involved in the P450-catalyzed hydroxylation pathway of a natural product derivative methyl cinnamate, which indicates that this intermediate appears to be universal in P450-catalyzed aromatic hydroxylation.
