  Spectroscopic evidence for a spirooxirane intermediate in the synthesis of 4-(hydroxymethyl)-2-[(dimethylamino)methyl]thiazole

  摘要：

  The synthesis of 4-(hydroxymethyl)thiazole derivatives from the corresponding 4-(chloromethyl)-4-Hydroxythiazole derivatives have been speculated to proceed through spirooxirane intermediates. NMR spectroscopy was used to provide evidence for the existence of such an intermediate in the synthesis of 4-(hydroxy-methyl)-2-[(dimethylamino)methyl]thiazole. Experimental conditions for the optimum formation and stabilization of a suspect intermediate were determined and spectral data obtained to support the speculated structure. Comparisons were made between couplings constants predicted in molecular models and the experimental data.
