TFA-catalyzed C–N bond activation of enamides with indoles: efficient synthesis of 3,3-bisindolylpropanoates and other bisindolylalkanes
摘要:
An efficient TFA-catalyzed cleavage of C-N bonds in alkylation of indoles by tertiary enamides was described. A variety of bisindolylalkane derivatives, especially 3,3-bisindolylpropanoates, were expeditiously synthesized in good yields. (c) 2012 Elsevier Ltd. All rights reserved.

Pd(II)-catalyzed oxidative coupling previously. Detailed investigations revealed that the reaction proceeds by heterobimetallic Pd(II)/Sc(III)-catalyzed oxidative coupling of an indole with an olefin followed by Sc(III)-catalyzed addition with a second indole molecule. DFT calculations disclosed that the formation of heterobimetallic Pd(II)/Sc(III) species substantially decreases the C–H bond activation
