Maiorova, V. I. Karmanov, A. A. Gorbunov, P. A. Slepukhin // Russian Journal of Organic Chemistry (Translation of Zhurnal Organicheskoi Khimii). - 2012. - Vol.48, №4. - С. 575-581 Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): SPIROCYCLOHEXADIENONE -- ENAMINES -- DIHYDROISOQUINOLINES Аннотация: Addition of 1,3,3-trimethyl-3,4-dihydroisoquinolines to N-benzylideneanilines gives substituted N-[2-(3,3-dimethyl-3,4-dihydroisoquinolin-1-yl)-1-phenylethyl]anilines, whereas 2′,5′,5′-trimethyl-4′,5′-dihydro-4H-spiro[naphthalene-1,3′-pyrrol]-4-one reacts with N-benzylideneanilines along two pathways involving cyclization to substituted 2,3,3a,4,10,11-hexahydrobenzo[f]pyrrolo[2,3-d]quinolin-5(1H)-ones or elimination of the aniline residue with formation of substituted 5′,5′-trimethyl-2-styryl-4′,5′-dihydro-4H-spiro[naphthalene-1,3′-pyrrol]-4-ones \\\\Expert2\\nbo\\Russian Journal of Organic Chemistry\\2012, 48 (4), 575-581.pdf |
