title: 6pi-Photocyclization of O-tert-butylacrylanilides. N-substitution dictates the regiochemistry of cyclization.
abstract: O-tert-Butylacrylanilides with N-H substitution undergo 6pi-photocyclization at the unsubstituted ortho carbon, whereas the corresponding N-methyl derivatives cyclize at the ortho carbon bearing the tert-butyl with the eventual loss of 2-methylpropene.
