Abstract

For investigation of decomposable scaffolds for the fezolinetant triazopiperazine core in the natural environment, an efficient method for synthesis of [1,2,4]triazolo[4,3-a]piperazine derivatives was established based on gold(I)-catalyzed domino cyclization of an amidrazone substrate with a terminal alkyne. The amidoxime congeners were also converted into [1,2,4]oxadiazolo[4,5-a]piperazine derivatives in the presence of a gold catalyst.
