Photocyclisation and photoracemisation of 1-(o-α-methylbenzyl)phenylpropane-1,2-dione
Abstract
Optically active 1-(o-α-methylbenzyl)phenylpropane-1,2-dione undergoes photoracemisation concurrently with photocyclisation to 2-hydroxyindan-1-one derivatives, the epimers of which are formed with the same optical purity.
