Abstract
(E)-1-(4-Methoxyphenyl)-3-[4-(prop-2-ynyloxy)phenyl]prop-2-en-1-one undergoes a cyclocondensation reaction with thiosemicarbazide to form the corresponding 4,5-dihydropyrazole-1-arbothioamide, which in turn undergoes further cycloaddition with phenacyl bromides to form 4,5-dihydro-1-(thiazol-2-yl)pyrazoles. The molecules adopt an overall T-shape structure. Different combinations of hydrogen bonds link the molecules into ribbons or sheets.
