Alkyl 3-(2-aminoethyl)-1H-indole-2-acetates 6a and 6b are synthesized starting from methyl 1H-indole-2-acetate (2)via methyl 3-(2-nitroethenyl)-1H-indole-2-acetate (4) and the alkyl 3-(2-nitroethyl)-1H-indole-2-acetates 5a and (Scheme 1). Analogously, diisopropyl 3-(2-aminoethyl)-1H-indole-2-malonate 20b is obtained from diisopropyl 1H-indole-2-malonate 11c(Scheme 4). An alternative synthesis of 20a
