Palladium acetate mediated synthesis of 3,4-benzo and naphtho-β-carbolines
Jeevanandam,Srinivasan
, p. 3427 - 3434 (2007/10/03)
An efficient synthesis of 2-(N-arylaminomethyl)indole derivatives 5 in good yields in four steps from 2-bromomethyl-3-phenylthio-1-benzenesulfonyl indole1 is reported. Palladium acetate mediated cyclisation of 5 gives benzo and naphtho-β-carbolines (6 and 7).
