4-Phenylbut-3-yne-2-one reacts with αω-diamino-ethane and -propane either by condensation or by conjugate addition, dependant on the reaction conditions, but cyclisation products were not obtained. 2-Aminoethanethiol reacts with this ynone by conjugate addition of the amino-group, with benzylideneacetone to give a tetrahydrothiazepine, and with chalcone to give mono- or bis-conjugate addition products.
