Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): TERT-AMINO EFFECT -- PYRAZOLONE -- DIASTEREOMERS Аннотация: Cyclization of 2 (4 R piperidino)benzaldehydes with 5 methyl 2 phenyl 2,4 dihydro 3H pyrazol 3 one proceeding via tert amino effect mechanism is stereoselective. Relative configu ration of (3R*,4aS*,5R*) 2,3,4,4a,5,6 hexahydro 1H benzo[c]quinolizine was established on the base of NMR spectroscopy data and X ray analysis \\\\expert2\\NBO\\Russian Chemical Bulletin\\2011, 60 (5), 961-964.pdf |
