摘要

Chemistry of Heterocyclic Compounds, Vol. 43, No. 1, 2007 ... SPIRO[BENZO[c]QUINOLIZINE -5,4'-PYRAZOL]-5'-ONES ... TV Glukhareva, PE Kropotina, MF Kosterina, Yu. I. Nein, ... The synthesis of 2,3,4,4a,5,6-hexahydro-6H-spiro[benzo[c]quinolizine-5,4'-pyrazol]-5'-ones has been achieved by the reaction of 2-piperidinobenzaldehydes with 2-aryl-5-methyl-2,4-dihydropyrazol -3-one via the "tert-amino effect" mechanism. ... Keywords: pyrazol-3-one, ...
