Facile Route to 1,3-Diazaheterocycle-Fused [1,2b]Isoquinolin-1(2H)-one Derivatives via Substitution-Cyclization Reactions
摘要:
The substitution-cyclization reaction of heterocyclic ketene aminals with polyhalo isophthalonitrile in the presence of t-BuOK to form 1,3-diazaheterocycle fused [1,2-b]isoquinolin-1(2H)-imines, followed by hydrolysis with 1N HCl, provides a concise and efficient route for the synthesis of highly functional polyhalo 1,3-diazaheterocycle fused [1,2-b]isoquinolin-1(2H)-ones.

A series of polyhalo heterocyclic ketene aminals (polyhalo-HKAs) were synthesized under solvent-free conditions and evaluated in vitro against a panel of human tumor cell lines. Trifluoro-HKAs were the most cytotoxic compounds, followed by difluoro-HKAs and trichloro-HKAs. Trichloro-HKAs were more potent against the tumor cell lines Skov-3, Hep-2, K562, and A431 than difluoro-HKAs. An ethoxycarbonyl
