| Abstract: | Allylthiourea derivatives were synthesized from the alkaloids cytisine and anabasine and allylisothiocyanate. 1,3-Thiazoline
derivatives were synthesized from them via intramolecular heterocyclization using HCl and heating in a sealed ampul. The structures
of the synthesized compounds were proved by IR and PMR spectroscopy, mass spectrometry, and x-ray structure analysis. |
