  The highly enantioselective synthesis of α‐methyl‐substituted esters is reported in up to 90% yield and up to 99% ee using copper‐TaniaPhos as chiral catalyst. The transformation proved scalable to at least 6.6 mmol (1.7 g scale). The products of this transformation have been further elaborated to multifunctional building blocks with a single (branched esters and acids) or multiple stereogenic centers

  据报道，使用铜-TaniaPhos作为手性催化剂，α-甲基取代酯的高度对映选择性合成产率高达90％，ee高达99％。该转化证明可扩展至至少6.6 mmol（1.7 g规模）。这种转化的产物已被进一步精制为具有单个（支链酯和酸）或多个立体中心（邻位二甲基酯以及羟基或碘取代的内酯）的多功能构件。

  3R)--hydroxyesters in high optical purity. The corresponding (2R,3R)- isomer was obtained, with other strains, only in mixture with the isomer. These esters are useful precursors for chiral 2-methyl-3-hydroxy-butyrolactone synthons.

  几种真菌菌株对4-O-苄基-2-甲基-3-氧代丁酸酯的还原主要产生高光学纯度的（2S，3R）-羟基酯。仅在与异构体混合的情况下，与其他菌株一起获得了相应的（2R，3R）-异构体。这些酯是用于手性2-甲基-3-羟基-丁内酯合成子的有用的前体。
• The antibacterial properties of 6-tuliposide B. Synthesis of 6-tuliposide B analogues and structure–activity relationship

  6-Tuliposide B is a secondary metabolite occurring specifically in tulip anthers. Recently, a potent antibacterial activity of 6-tuliposide B has been reported. However, its molecular target has not yet been established, nor its action mechanism. To shed light on such issues, 6-tuliposide B and tulipalin B analogues were synthesized and a structure-activity relationship (SAR) was examined using a broad panel of bacterial strains. As the results of SAR among a total of 25 compounds, only tulipalin B and the compounds having 3',4'-dihydroxy-2'-methylenebutanoate (DHMB) moieties showed any significant antibacterial activity. Moreover, the 3'R analogues of these compounds displayed essentially the same activities as 6-tuliposide B and the structure of the 3'R-DMBA moiety was the same as that of the proposed active moiety of cnicin. These results suggest that 6-tuliposide B has the same action mechanism as proposed for cnicin and bacteria) MurA is one of the major molecular targets of 6-tuliposide B. (C) 2009 Elsevier Ltd.
