Regioselective Nitration of N(α),N(1)-Bis(trifluoroacetyl)-L-Tryptophan Methyl Ester: Efficient Synthesis of 2-Nitro and 6-Nitro-N-Trifluoroacetyl-L-Tryptophan Methyl Ester
Nitration of N(α),N(1)-bis(trifluoroacetyl)-L-tryptophan methyl ester with HNO(3) in acetic anhydride at 0° C provides N(α)-trifluoroacetyl-2-nitro-L-tryptophan methyl ester in 67% yield, whereas nitration in trifluoroacetic acid at 0° C gives N(α)-trifluoroacetyl-6-nitro-L-tryptophan methyl ester i...
