An efficient regiocontrolled synthesis of highly substituted and annulated indazoles involving base induced addition-elimination of 1,3-diphenyl-5- cyanomethylpyrazole to a variety of acyclic and cyclic α-oxoketene, followed by acid assisted cycloaromatization of the resulting conjugate adducts has been reported.
