The enantioselective synthesis of siastatinB, an inhibitor of neuraminidase and its antipode from D-ribono-γ-lactone has stereospecifically been achieved. The totalsynthesis elucidated the absoluteconfiguration of siastatinB as (3S,4S,5R,6R)-6-acetamido-4,5-dihydroxy-3-piperidinecarboxylic acid.
已立体特异性地实现了对映选择性合成 siastatin B、神经氨酸酶抑制剂及其来自 D-核糖-γ-内酯的对映体。全合成阐明了 siastatin B 的绝对构型为 (3S,4S,5R,6R)-6-乙酰氨基-4,5-二羟基-3-哌啶羧酸。

total synthesis of corramycin, a myxobacterial naturalproduct of the strain Corallococcus coralloides, is presented. The synthetic strategy included using two consecutive chemical ligations for a modular and efficient preparation. Finally, the synthesis employed a Ser/Thr ligation (STL) at a new ligation site combined with classical fragmentcoupling. This study provides the total synthesis of corramycin
