Abstract
Multifunctionalized 2-imino-3-(pyrazol-4-yl)thiazolidin-4-ones and 2-arylimino-3-(pyrazol-4-yl)thiazolidin-4-ones were prepared according to an efficient four-step procedure. The key step of the synthetic pathway involved the cyclization of 2-chloro-N-(pyrazol-4-yl)acetamide intermediate using KSCN or aryl isothiocyanate, respectively. The structure of the title compounds was confirmed on the basis of NMR data and 15N-labeling.
