Photochemistry of 2-indolyl aryl ethers: An unexpected rearrangement leading to C-C bond formation

Feldman, Ken S.,Vidulova, Daniela Boneva

, p. 1615 - 1623 (2007/10/03)

Two types of 2-(p-tolyloxy)indole were prepared and their reactivity was studied under photochemical conditions. The expected electrocyclization was not observed. Instead, unprecedented rearrangement products were obtained. The reaction outcome was found to depend on the viscosity of the media.
