One-Pot Synthesis and Antiproliferative Activity of Highly Functionalized Pyrazole Derivatives
Iervasi, Erika,Lusardi, Matteo,Ponassi, Marco,Rosano, Camillo,Rotolo, Chiara,Spallarossa, Andrea
, (2022/02/05)
A series of highly functionalized pyrazole derivatives has been prepared by a one-pot, versatile and regioselective procedure. Pyrazoles 1–29 were tested in cell-based assay to assess their antiproliferative activity against a panel of tumour cells. Addit

Various functionalised 4-amino-2-(methylthio)quinolines are synthesised through triflic acid-mediated N-heteroannulation of α-functionalized-β-anilino-β-(methylthio)acrylonitriles for the first time. The N-heteroannulation process is highly chemoselective and has mild reaction conditions. However, this process fails in the absence of the β-methylthio group in the acrylonitriles. In addition, a new double N-heteroannulation process is demonstrated to synthesise indolo[3,2-c]quinolines from non-heterocyclic precursors. Natural product isocryptolepine is synthesised in four steps from an acyclic precursor.
