An unusual rearrangement/thietane ring formation results from the treatment of an 3-chloro-2-hydroxypropyl iminothioether with base. 6-Oxo-1-(thietan-3-yl)-purine (3) was characterized by spectral analysis and conversion to thientanyl 5-amino-4-carboxamidoimidazole (6) whose structure was confirmed by x-ray analysis.
