We described in this paper an efficient synthesis of variously substituted 4-phosphinoyl-4,5,6,7-tetrahydro-2H-indazol-3-ylamines involving nucleophilic addition of hydrazine on β-ketothioamides as key-step. © 2011 Elsevier Ltd. All rights reserved. Source

The condensation of primary amines on - or -ketophosphonates affords the corresponding iminophosphonates. The reaction was found to be highly stereoselective, affording the E isomer exclusively. These phosphonylimines were then treated in basic media to give pyrrolidines and quinolines through intramolecular cyclization. The structures of all obtained products were confirmed by NMR spectroscopy (1H, 31P, 13C), and in some cases by mass spectrometry. Copyright © Taylor & Francis Group, LLC. Source
