Photo-induced rearrangement of 1-ethoxy-2-phenylindole
Yamada, Koji,Somei, Masanori
, p. 2481 - 2484 (2007/10/03)
Photoirradiation of 1-ethoxy-2-phenylindole in methanol afforded 3- and 6-ethoxy-2-phenylindoles. The structural determination of the latter is carried out by direct comparison of its spectral data with those of the authentic 4-, 5-, 6-, and 7-ethoxy-2-phenylindoles, whose syntheses are also included.
