3-OXO-INDAZOLINE AND 4-OXO-DIHYDROQUINAZOLINE DERIVATIVES FROM ISATIC ACIDS

The coupling of diazonium salts from isatic acids with alkoxycarbonylmethylenephosphoranes leads directly to 3-oxo-indazolin-2-yl-(alkoxycarbonyl)methylenetriphenylphosphoranes, while coupling with methyl 2-chloroacetacetate gives 2-phenyl-glyoxylic acid.
