The reaction of 4-amino-8-hydroxy-1,6-dioxo-2,7-diazaspiro[4.4]non-3-ene-4-carbonitriles with Lawesson's reagent proceeded as an iminothiolactone-thiolactam rearrangement, leading to the formation of 4-amino-6-thioxo-3,7,9-triazatricyclo[6.2.1.01,5]undec-4-ene-2,10-diones.
4-氨基-8-羟基-1,6-二氧杂2,7-二氮杂螺[4.4]非-3-烯-4-腈与Lawesson试剂的反应以亚氨基硫代内酯-硫代内酰胺重排进行,导致形成4-氨基-6-thioxo-3,7,9-三氮杂三环[6.2.1.0 1,5 ]十一碳-4-烯-2,10-二酮。
