Hack, Daniel published the artcileAsymmetric Synthesis of Spiropyrazolones by Sequential Organo- and Silver Catalysis, Application In Synthesis of 14580-22-4, the publication is Angewandte Chemie, International Edition (2016), 55(5), 1797-1800, database is CAplus and MEDLINE.

A stereoselective one-pot synthesis of spiropyrazolones, e.g., I, through an organocatalytic asym. Michael addition and a formal Conia-ene reaction has been developed. Depending on the nitroalkene, the 5-exo-dig-cyclization could be achieved by silver-catalyzed alkyne activation or by oxidation of the intermediate enolate. The mechanistic pathways have been investigated using computational chem. and mechanistic experiments
