FeCl3·6H2O-Catalyzed Alkenylation of Indoles with Aldehydes
摘要:
FeCl3 center dot 6H(2)O-catalyzed efficient C3-alkenylation of indoles was realized through the condensation of aldehydes and indole derivatives in the presence of 2 equiv of ethanol at ambient temperature, forming 3-vinylindoles in up to 93% yields. Ethanol promoted formation of the desired products. An obvious solvent effect was observed, and bisindoles were identified as the reaction intermediates.
