FORMATION OF FURO- AND DIFURO-1,4-DIHYDROPYRIDINES IN THE BROMINATION OF 2,6-DIMETHYL-3,5-DIMETHOXYCARBONYL-4-(o-NITROPHENYL)-1,4-DIHYDROPYRIDINE

Skrastin'sh, I. P.,Kastron, V. V.,Dubur, G. Ya.,Mazheika, I. B.,Kadysh, V. P.

, p. 981 - 985 (2007/10/02)

Furo- and difuro-1,4-dihydropyridines were obtained by bromination of 2,6-dimethyl-3,5-dimethoxycarbonyl-4-(o-nitrophenyl)-1,4-dihydropyridine with mild brominating agents (pyridinium bromide perbromide, N-bromosuccinimide, and dioxane dibromide).
