Indium triflate-catalyzed coupling of indoles with acyl phosphonates: synthesis of bis(indolyl)methane phosphonates
摘要:
The coupling reaction of N-methylindole with alkyl and aryl phosphonate is described. The reaction works in the presence of 10 mol % of indium triflate and furnished bis(indolyl)methane phosphonates in good yield and high selectivity. (C) 2011 Elsevier Ltd. All rights reserved.
