Formation of blue diquinolinyl methine dyes by irradiation of N-acylated primaquine in chloroform solution with ultraviolet light

Gessner, Wieslaw P.,Venugopalan Bindumadhavan,Brossi, Arnold

, p. 2196 - 2198 (2007/10/02)

Irradiation of N-acylated primaquines 1b-d in chloroform solution with ultraviolet light afforded blue diquinolinyl methine dyes 3b-d.The structures of compounds 3b-d are supported by spectral data, synthesis of 3c from 1c with orthoformate, and chemical reduction of 3d affording known dimer 5d.
