6-Substituted 7,8,9,10-tetrahydrophenanthridin-7-one system was prepared from 3-(2-acylaminophenylthio)cyclohex-2-enones by dehydrative cyclization and concomitant sulfur extrusion with polyphosphoric acid in a single operation.
6 取代的 7、8、9、10-四氢菲啶-7-酮体系是由 3-(2-乙酰氨基苯硫基)环己-2-烯酮通过脱水环化和与多磷酸同时进行的硫挤压一次性制备而成。
