was obtained from 3-chloro-2-phenylindan-1-one (3), cyclizes on thermolysis to 5H-indeno[1,2-b]indol-10-one (5). Reaction of 3-azido-2-phenylindan-1-one (4) with triphenylphosphane gives 2-phenyl-3-(triphenylphosphoranylideneamino)-indan-1-one (6), which can be hydrolyzed to 3-amino-2-phenylindan-1-one (7). Attempts to perform a similar cyclization sequence with 3-chloro-2-pyridylindan-1-ones failed
3-叠氮基-2-苯基茚-1-酮(4),其从3-氯-2-苯基茚-1-酮(得3),热解上环化从而5 ħ -茚并[1,2 b ]吲哚-10-一个(5)。3-azido-2-phenylindan-1-one(4)与三苯基膦反应生成2-phenyl-3-(triphenylphosphoranylideneaminoamino)-indan-1-one(6),可以将其水解为3-amino-2-phenylindan -1-一(7)。尝试对3-chloro-2-pyridylindan-1-ones执行类似的环化序列失败。
