Copper(I)-catalyzed tandem cyclization/condensation reaction to novel 4,5-dihydropyrazolo[1,5-a]quinolines and pyrazolo[1,5-a]indoles

A facile copper(I)-catalyzed tandem reaction for the synthesis of 4,5-dihydropyrazolo[1,5-a]quinolines and pyrazolo[1,5-a]indoles is reported here. High efficiency and good yields are displayed in this transformation under mild reaction conditions.

Intramolecular Reaction of the Hydrazonyl Group with Formyl and Oxo Groups: Preparation of Pyrazoloindoles and Related Pyrazolo Compounds

Lewis acid-catalysed intramolecular nucleophilic attack of a hydrazonyl group onto aldehyde and ketone groups gives pyrazoles and dihydropyrazoles.Pyrazoloindoles and related pyrazolo compounds have also been prepared.

Preparation of Pyrazole and Pyrazoline Derivatives by Intramolecular Reaction of Hydrazones

Pyrazole and pyrazoline derivatives are prepared by the intramolecular cyclization reaction of a hydrazonyl group with formyl or keto groups in the presence of a Lewis acid.

Synthesis and pregnancy terminating activity of pyrazolo[1,5-a]indoles and quinolines

In order to clarify the structural requirements for antifertility activity, series of 2-arylpyrazolo[1,5-a]indoles and 2-arylpyrazolo[1,5-a]-quinolines were prepared and tested in rats and hamsters. Their potencies were compared with those of the isomeric
