Reflux of 3-cyanothiochromone with benzylamine in toluene afforded 17-benzyl-6,7,14,15-tetrahydro-7,15-epiminobis(8H,16H-dithiochromeno)[2,3-b:2′,3′-f][1,5]diazocine-6,14-dione, the self-condensation product of 2-amino-3-(benzyliminomethyl)thiochromone. Similar reaction with phenethylamine leads to 2-(thiochromon-3-yl)-5H-thiochromeno[2,3-d]-pyrimidin-5-one. Mechanism of formation of the dimeric products was considered.
3-氰基硫代色原酮与苄胺在甲苯中的回流反应生成17-苄基-6,7,14,15-四氢-7,15-亚氨基双(8H,16H-二硫代色烯)[2,3-b:2′,3′-f][1,5]二氮杂环辛烷-6,14-二酮,即2-氨基-3-(苄基亚氨基甲基)硫代色原酮的自缩合产物。与苯乙胺发生类似反应生成2-(硫代色原酮-3-基)-5H-硫代色烯并[2,3-d]-嘧啶-5-酮。研究了二聚体产物的形成机理。
