Abstract :
Photooxygenation (1O2) of ortho-prenylphenols followed by a reduction (PPh3) at low temperature (−30°C) yields a mixture of ortho-(2-hydroxy-3-methylbut-3-enyl)phenols and ortho-(3-hydroxy-3-methylbut-1-enyl)phenols. However, by running the two-step sequence at a higher temperature (15°C), the secondary allylic alcohol could be selectively recovered.
