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 at the 2-position of the polyhalo HKAs gave the highest activity. Ethoxycarbonyl substituted 5o, bearing three fluorine atoms on the isophthalonitrile ring, was found to be the most potent derivative with IC50 values lower than 3.7 μg/mL against five human tumor cell lines making it more active than cisplatin (DDP).
Facile route to 1,3-diazaheterocycle-fused [l,2b]isoquinolin-l(2H)-one derivatives via substitution-cyclization Reactions

The substitution-cyclization reaction of heterocyclic ketene aminals with polyhalo isophthalonitrile in the presence of I-BuOK to form 1,3-diazaheterocycle fused [1,2-fc]isoquinolin-l(2//)-imines, followed by hydrolysis with 1 N 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.
