Abstract: | 5-Aryl(hetaryl)furan-2,3-diones reacted with N-(triphenyl-λ5-phosphanylidene)-4,5,6,7-tetrahydro-1-benzothiophen-2-amines to give 5-aryl(hetaryl)-2-(4,5,6,7-tetrahydro-1-benzothiophen-2-yl)imino]furan-3(2H)-ones whose acid hydrolysis afforded 4-aryl(hetaryl)-2-hydroxy-4-oxo-N-(4,5,6,7-tetrahydro-1-benzothiophen- 2-yl)but-2-enamides. |
