The invention is related to compound which comprises at least one radical C═Y, Y being O or S, and an oxidable and non protonable nitrogen atom N wherein the distance (d) between the at least one carbon atom of the radical group C═Y and the nitrogen atom, when oxidized, is comprised between 0.3 and 0.8 nanometers. The invention is related to new heterocyclic compounds defined by formula G, their preparation, to pharmaceutical compositions comprising them and to their use as therapeutic agents, particularly in the treatment of neurodegenerative or Alzheimer disease.

alpha-Deamino-3-(beta-D-glucopyranosyloxy)krynurenine a yellow, fluorescent compound isolated from human lens, was synthesized in 8 steps (10% overall yield) from commercially available 3-methoxy-2-nitrobenzaldehyde. Key events included preparation and glucosylation of methyl 4-(3-hydroxy-2-nitrophenyl)-4-oxobutanoate followed by reduction of the nitro group and deprotection. (C) 2000 Elsevier Science Ltd.

日期:1996.1.1
N-Protected o- and p-anisidines (2- and 4-methoxyanilines) undergo a hydrogen/metal exchange at the position adjacent to either the oxygen or nitrogen atom depending on what organometalic base is employed. These synthetically useful findings support previous views about neighboring group/reagent interactions.
