摘要:
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.
