Novel Anionic Annelation Tactics for Construction of Fused Heteroaromatic Frameworks. 1. Synthesis of 4-Substituted Pyrazolo[4,3-c]quinolines, 9-Substituted Pyrazolo[3,4-c]quinolines, and 1,4-Dihydrochromeno[4,3-c]pyrazoles

4-Substituted pyrazolo[4,3-c]quinolines 4a−i and 6a−b were prepared from pyrazole 3 whereas 9-substituted pyrazolo[3,4-c]quinolines 9a−d and 17 were prepared from pyrazole 13 utilizing anionic annelation techniques. 1,4-Dihydrochromeno[4,3-c]pyrazoles 7a−c were accessed from pyrazole 3, extending the method for the synthesis of 4a−i.
