Synthesis of Spirocyclic Indolines by Interruption of the Bischler-Napieralski Reaction
The development of a versatile method for the synthesis of spirocyclic pyrrolidinoindolines is discussed. Treatment of N-acyltryptamines with trifluoromethanesulfonic anhydride-2-chloropyridine reagent combination affords highly persistent spiroindoleninium ions that are subject to intra- and interm...
