Conjugation of Phenothiazine and Substituted Indoles via Copper-Catalyzed 1,3-Dipolar Cycloaddition

Copper-catalyzed alkyne-azide 1,3-dipolar cycloaddition of substituted N-azidoalkylindoles and N-propargylphenothiazine led to the formation of conjugates of substituted indoles and phenothiazine combined with 1,2,3-triazole-containing alkylene spacers.
