Abstract

A synthetic approach to a structurally novel series of indoline 2, 2-biscarboxylates is described that employs a tandem bis-alkylation strategy to cyclize the indoline heteroring from the bromide 7 and diethyl bromomalonate. The indolines thus prepared may be N- deprotected and further functionalized on the indoline nitrogen.
