2-Alkylindoles via Wittig olefination of indole-2-aldehyde
Sadanandan, E. V.,Vedachalam, M.,Srinivasan, P. C.
, p. 481 - 483 (2007/10/02)
Oxidation of 3-phenylthio-2-phenylthiomethylindole (1) with N-bromosuccinimide affords 3-phenylthioindole-2-aldehyde (3) which undergoes Wittig reaction to give 2-vinyl derivatives (4a-c).The latter afford 2-alkylindoles (5a-c) upon Raney nickel treatment.
