The transposed Paternò−Büchi reaction involves a
ππ* excited state of
alkene reacting with a
ground state
carbonyl functionality. This is reversal of the traditional
Paternò−Büchi reaction where an excited carbonyl group reacts with a ground state alkene. This strategy was first reported by
Sivaguru and co-workers with reaction of
enamides.
