SYNTHESIS AND CHARACTERIZATION OF NEW INDOLE TRIMERS AND TETRAMERS
Bocchi Vittorio,Palla Gerardo
, p. 5019 - 5024 (2007/10/02)
A new method has been achieved to synthesize indole trimers and tetramers starting from indoles and 3-bromoindoles.Unusual open and cyclic trimers have been isolated and characterized, and the mechanism of formation is proposed.
