title: Facile route to 1,3-diazaheterocycle-fused [1,2b]Isoquinolin-1(2H)-one derivatives via substitution-cyclization reactions.
abstract: 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 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.
