2‐Aminoselenazoles with ethyl propiolate or dimethyl acetylenedicarboxylate gave 7 H ‐selenazolo[3,2‐ a ]pyrimidin‐7‐ones. 2‐Amino‐1,3,4‐selenadiazoles with dimethyl acetylenedicarboxylate gave 7 H ‐1,3,4‐selenadiazolo[3,2‐ a ]pyrimidin‐7‐ones; with ethyl propiolate the reaction took an unusual path and 2‐carbethoxy‐5 H ‐selenazolo[3,2‐ a ]pyrimidin‐5‐one was isolated. The assignment of the structures were supported by spectra analysis.
