Заглавие : Aminomethylation of chlorophyll a derivatives using bis(N,N-dimethylamino) methane Место публикации : Journal of Porphyrins and Phthalocyanines. - 2009. - Vol. 13, № 7-8. - С. 949-956 ББК : 54 Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: Bis(N,N-dimethylamino)methane has been shown to be a convenient reagent for the aminomethylation of chlorophyll a derivatives. Methylpheophorbide a (in enol form) and chlorin e6 13-amides were aminomethylated with bis(N,N-dimethylamino)methane. Reactivity of methylpheophorbide a exo-ring and chlorin e6 13-amides vinyl group were shown to be different. Selective methylpheophorbide a exo-ring aminomethylation was realized and isomerization of the exo-ring aminomethylation product with rhodochlorin 15-acrylic derivative formation was studied. The action of bis(N,N- dimethylamino)-methane in the presence of weak acid has been shown to be a simple and effective synthetic procedure to obtain a new chlorin e6 derivative with two N,N-dimethylaminomethyl substituents in the vinyl group. The aminomethylation products' high yields, the simplicity of the procedure, the use of metal-free chlorines and the possible synthesis of new compounds, were found to be the main advantages of using bis(N,N-dimethylamino)methane as an aminomethylation reagent in chlorophyll a derivatives' chemistry Держатели документа: Центральная научная библиотека УрО РАН Доп.точки доступа: Belykh, D.V.; Tarabukina, I.S.; Gruzdev, D.A.; Kodess, M.
