addressable protecting groups from dihalomethane C1-units is reported. The underlying synthesis of C6-sugar alcohols relies on three consecutive Matteson sequences, vinylation and bishydroxylation. Erythro and threoisomers have been realized for every glycol motif by strategic variation of the sequence.
报道了所有具有来自二卤甲烷C 1 -单元的可单独寻址保护基团的己醛糖的合成策略。 C 6 -糖醇的基本合成依赖于三个连续的Matteson序列、乙烯基化和双羟基化。通过序列的策略性变化,已经实现了每个二醇基序的赤式和苏式异构体。

The syntheses of 2-bromo-3-dehydroshikimic acid(1) (5) and 2-bromoshikimic acid(2) (8), are described. Their formation from (2R)-2-bromo-3-dehydroquinic acid (2) using dehydroquinase and shikimate dehydrogenase is also reported. The corresponding enzymatic formation of 2-fluoro-3-dehydroshikimic acid(1) (6) and 2-fluoroshikimic acid(2) (9) from (2R)-2-fluoro-3-dehydroquinic acid (3) are reported.
