Abstract: 1,3,4,6-Tetracarbonyl compounds undergo a series of cascade condensations with thiocarbonohydrazide to form substituted pyrazolo[1,5- d ][1,2,4]triazines. The studied transformations proceed in good yields under catalyst-free conditions, and the reaction products are isolated without the use… read more here.

Abstract: The reaction of 1,3-bis(silyloxy)-1,3-butadienes with functionalized and nonfunctionalized acid chlorides and bis(acid chlorides) gives rise to the formation of a great variety of 1,3,5-tri- and 1,3,5,7-tetracarbonyl compounds and cyclic products derived from them. Examples include… read more here.
