The title compound was synthesized from methyl 4-O-benzyl-2,6-dideoxy-β-L-threo-hexopyranosid-3-ulose (19) through cyanomesylation, reductive spiro aziridine formation, and reductive ring-opening. When (2-methoxyethoxymethyl) group was used as the protecting group at O-4 of the above intermediate, it could not be removed at the final stage.
标题化合物由甲基 4-O-benzyl-2,6-dideoxy-β-L-threo-hexopyranosid-3-ulose (19) 通过氰基甲基化、还原性螺环氮丙啶形成和还原性开环合成。当(2-甲氧基乙氧基甲基)基团用作上述中间体的O-4处的保护基团时,它不能在最后阶段去除。
