Abstract :
A new class of thiazolo[3,2-a]imidazole derivatives is obtained in good yields, by reacting 1-methyl-2-bromoimidazolium salts bearing N+-CH2COAr, N+-CH2COMe, N+-CH2COOMe, or N+-CH2CN fragments, with carbon disulfide in the presence of Et3N at room temperature. The mesoionic structures of these compounds are established by NMR spectroscopy and by single-crystal X-ray analysis.
